AB  - : Post-translational modifications (PTMs) are covalent changes occurring on amino acid side
chains of proteins and yet are neglected structural and functional aspects of protein architecture. The
objective was to detect differences in PTM profiles that take place after roasting using open PTM
search. We conducted a bottom-up proteomic study to investigate the impact of peanut roasting on
readily soluble allergens and their PTM profiles. Proteomic PTM profiling of certain modifications
was confirmed by Western blotting with a series of PTM-specific antibodies. In addition to inducing
protein aggregation and denaturation, roasting may facilitate change in their PTM pattern and relative
profiling. We have shown that Ara h 1 is the most modified major allergen in both samples in terms
of modification versatility and extent. The most frequent PTM was methionine oxidation, especially
in roasted samples. PTMs uniquely found in roasted samples were hydroxylation (Trp), formylation
(Arg/Lys), and oxidation or hydroxylation (Asn). Raw and roasted peanut extracts did not differ
in the binding of IgE from the serum of peanut-sensitised individuals done by ELISA. This study
provides a better understanding of how roasting impacts the PTM profile of major peanut allergens
and provides a good foundation for further exploration of PTMs

AB  - Post-translational modifications (PTMs) occur in many forms and shapes, widely influencing protein behavior. High-resolution tandem mass spectrometry (HRMS/MS), coupled with dedicated engines for the identification of unspecified PTMs, is a powerful method for their mapping. 
A majority of proteomic experiments utilize trypsin for digestion, which cleaves the C-terminal peptide bonds of arginine (Arg) and lysine (Lys) amino acids with high catalytic efficiency and selectivity, unless they are followed with proline. At the same time, Arg and Lys residues are frequently modified during food processing by heat and non-thermal treatments, causing oxidation, carbamylation, and various forms of side chain carbonylation, including the other common PTMs (methylation, acetylation, etc.). Consequently, we explored the possibility to re-assess already generated proteomic data (food protein/allergen tryptic peptides) with respect to the possible modulation of the tryptic intestinal digestion pattern caused by PTMs incorporated at Arg and Lys residues. However, most of the proteomic bottom-up experiments are run with porcine trypsin that has been reductively methylated to increase its stability and minimize autoproteolytic effects. Therefore, in this chapter, the utility of the aforementioned idea was explored, by reviewing the differences in structure, affinity, specificity, and catalytic efficiency of trypsin, primarily from porcine, bovine and human species. Porcine trypsin either from pancreas or in recombinant form showed superior performance compared to human and bovine tryptic counterparts. In addition, set of software tools for identification and analyses of PTMs was reviewed with the aim to isolate those capable of in-depth PTMs profiling and their simultaneous relative quantification, such as PEAKS PTM (PEAKS Studio, Bioinformatics Solution Inc., Ontario Canada). Based on our preliminary experimental results, conclusion is that the proposed idea is plausible, because if potential hindrance effects caused by PTMs are observed with porcine trypsin, then they can be just augmented within human intestinal digestion, with respect to inferior performance of human trypsin.

AB  - The reactions of four cymene-capped ruthenium(II) compounds with pro-apaptotic protein, cytochrome c (Cyt), and anti-proliferating protein lysozyme (Ly) in carbonate buffer were investigated by ESI-MS, UV–Vis absorption and CD spectroscopy. The complexes with two chloride ligands (C2 and C3) were more reactive toward proteins than those with only one (C1 and C4), and the complex with S,N-chelating ligand (C4) was less reactive than one with O,N-chelating ligand (C1). Dehalogenated complexes are most likely species initially coordinating proteins for all tested complexes. During the time, protein adducts vividly exchanged non-arene organic ligand L with CO32- and OH-, while cymene moiety was retained. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could generate different intermediate protein species. Although all complexes reduced Cyt, the reduction was not dependent on their reactivity to protein, implying that initially noncovalent binding to Cyt occures, causing its reduction, followed by coordination to protein. Cyt reduction was accompanied with rupture of ferro-Met 80 and occupation of this hem coordination site by a histidine His-33/26. Therefore, in Cyt with C2 and C3 less intensive reduction of hem iron leave more unoccupied target residues for Ru coordination, leading to more efficient formation of covalent adducts, in comparison to C1 and C4. This study contribute to development of new protein-targeted Ru(II) cymene complexes, and to design of new cancer therapies based on targeted delivery of Ru(II) arene complexes bound on pro-apoptotic/anti-proliferating proteins as vehicles.

During the time, protein adducts vividly exchanged non-arene organic ligand L with CO32- and OH-, while cymene moiety was retained. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could generate different intermediate protein species. Although all complexes reduced Cyt, the reduction was not dependent on their reactivity to protein, implying that initially noncovalent binding to Cyt occures, causing its reduction, followed by coordination to protein. Cyt reduction was accompanied with rupture of ferro-Met 80 and occupation of this hem coordination site by a histidine His-33/26. Therefore, in Cyt with C2 and C3 less intensive reduction of hem iron leave more unoccupied target residues for Ru coordination, leading to more efficient formation of covalent adducts, in comparison to C1 and C4. This study contribute to development of new protein-targeted Ru(II) cymene complexes, and to design of new cancer therapies based on targeted delivery of Ru(II) arene complexes bound on pro-apoptotic/anti-proliferating proteins as vehicles.",

AB  - The reactions of four cymene-capped ruthenium(II) compounds with pro-apaptotic protein, cytochrome c (Cyt), and anti-proliferating protein lysozyme (Ly) in carbonate buffer were investigated by ESI-MS, UV–Vis absorption and CD spectroscopy. The complexes with two chloride ligands (C2 and C3) were more reactive toward proteins than those with only one (C1 and C4), and the complex with S,N-chelating ligand (C4) was less reactive than one with O,N-chelating ligand (C1). Dehalogenated complexes are most likely species initially coordinating proteins for all tested complexes. During the time, protein adducts vividly exchanged non-arene organic ligand L with CO32- and OH-, while cymene moiety was retained. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could generate different intermediate protein species. Although all complexes reduced Cyt, the reduction was not dependent on their reactivity to protein, implying that initially noncovalent binding to Cyt occures, causing its reduction, followed by coordination to protein. Cyt reduction was accompanied with rupture of ferro-Met 80 and occupation of this hem coordination site by a histidine His-33/26. Therefore, in Cyt with C2 and C3 less intensive reduction of hem iron leave more unoccupied target residues for Ru coordination, leading to more efficient formation of covalent adducts, in comparison to C1 and C4. This study contribute to development of new protein-targeted Ru(II) cymene complexes, and to design of new cancer therapies based on targeted delivery of Ru(II) arene complexes bound on pro-apoptotic/anti-proliferating proteins as vehicles.

AB  - The selective hydrolysis of proteins by non‐enzymatic catalysis is difficult to achieve, yet it is crucial for applications in biotechnology and proteomics. Herein, we report that discrete hafnium metal‐oxo cluster [Hf18O10(OH)26(SO4)13⋅(H2O)33] (Hf18), which is centred by the same hexamer motif found in many MOFs, acts as a heterogeneous catalyst for the efficient hydrolysis of horse heart myoglobin (HHM) in low buffer concentrations. Among 154 amino acids present in the sequence of HHM, strictly selective cleavage at only 6 solvent accessible aspartate residues was observed. Mechanistic experiments suggest that the hydrolytic activity is likely derived from the actuation of HfIV Lewis acidic sites and the Brønsted acidic surface of Hf18. X‐ray scattering and ESI‐MS revealed that Hf18 is completely insoluble in these conditions, confirming the HHM hydrolysis is caused by a heterogeneous reaction of the solid Hf18 cluster, and not from smaller, soluble Hf species that could leach into solution.

AB  - The ruthenium-based antitumour compounds act more via protein targets involved in carcinogenesis, in contrast to platinum-based compounds. Also, after intravenous administration of antitumour complexes proteins are the first binding targets in circulation. Therefore, interactions of anticancer compounds with proteins are important for elucidation of their pharmacokinetic pathways. Four half-sandwich ruthenium(II)-cymene complexes (C1, C2, C3 and C4), developed earlier and with promising cytotoxic activity, are investigated for their interactions with cytochrome c (Cyt). Complexes  were incubated with Cyt for 48 h at 37 °C and high-resolution LTQ-Orbitrap ESI MS was used to monitor the formed adducts. The changes in heme state and tertiary structure around the heme were monitored by CD and UV-VIS spectra in the presence of oxygen. The complexes containing two chloride ligands (C2 and C3) were more reactive toward Cyt than those with only one (C1 and C4). The complex with S,N-chelating ligand (C4) was less reactive than one with O,N-chelating ligand (C1). All complexes reduced heme iron of Cyt, but the extent of reduction was inverse to the order of their reactivity to Cyt (C1>C4>>C2>C3). CD spectra in Soret region indicated that Cyt reduction was accompanied with slight tertiary structure change, the rupture of ferro-Met-80 and occupation of this heme coordination site by His-33/His-26. Extent of  heme reduction by complexes inverse with respect to their reactivity implies that initially noncovalent binding of complexes occures, causing heme reduction, followed by comlex coordination to protein. In the presence of less reactive complexes more intensive reduction of heme leaves less available histidine residues (main targets for Ru coordination), leading to less efficient formation of adducts.

AB  - Objective. In contrast to platinum-based antitumour compounds, the mode of action of ruthenium-based compounds is via protein targets involved in cellular signaling pathways and the histone proteins. As proteins are the first potential binding targets for the complexes in the bloodstream after their intravenous administration, interactions of anticancer therapeutics with proteins are very important to be investigated with aim to elucidate their pharmacokinetic pathways. Four half-sandwich ruthenium(II)-cymene complexes, developed earlier and with promising cytotoxic activity, are investigated  for their interactions with proteins, cytochrome c and lysozyme.

Material and Methods. Ruthenium(II)-cymene complexes were incubated for 24 and 48 h at 37 °C in the presence of cytochrome c and lysozyme, both in 20 mM ammonium hydrogen carbonate pH 7.4 and water. High-resolution LTQ-Orbitrap ESI MS was used to monitor the adducts formed between ruthenium complexes and proteins.

Results. The complexes with two Cl- ligands have shown higher reactivity to proteins than those with only one, and were more reactive toward cytochrome c in comparison to lysozyme. The complex with S,N-chelating ligand was less reactive to proteins than one with O,N-chelating ligand. Species initially coordinating the proteins are most likely dehalogenated complexes. During the time, vivid ligand exchange of non-arene organic ligand L with CO32- and OH- takes place after initial formation of protein adducts. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could be expected generating different intermediate protein species. 

Conclusions. Protein reactivity toward Ru(II) complexes is determined by protein structure and ligands in Ru(II) coordination sphere, but this reactivity should be described from both kinetics, as well as stability aspect. In extracellular or intracellular milieu, ability of metal binding ligands (such as carbonate ions) to bind and to leave, determinate both the extent and mechanism of the binding of ruthenium complexes to the target biomacromolecules for cancer therapy.

AB  - Brief introduction: Stability to gastric digestion represents a very important parameter of food protein allergenicity. Usually digestion experiments are carried out on purified proteins or protein extracts; however, use of solid food is far closer to the in vivo situation, taking into account food protein interactions with other food components, such as polyphenols and lipids.
Objective: The aim of this study was to investigate and compare digestion stability and allergenicity of large and small peptides released after pepsin digestion of whole raw and roasted hazelnut kernels under standardized and physiologically relevant in vitro conditions.
Methodology: In vitro simulated oral and gastric phase digestion was carried out with ground raw and roasted hazelnut kernels. Digested proteins were extracted from the mixture and analyzed by SDS-PAGE, 2D-PAGE, and compared with Image Master 2D Platinum 7.0. Western blot probed with allergic patients’ sera and specific antibodies for Cor a 8.
Main findings: Several important hazelnut seed storage digestion resistant proteins and peptides have been identified and characterized. Most abundant hazelnut allergens were resolved on a 2DE map, for instance acidic and basic chains of Cor a 9, and Cor a
11. Digestion-resistant peptides of Cor a 11 and Cor a 9 were able to bind IgE. Lipid transfer protein (Cor a 8) was highly resistant to gastric proteolysis. Conclusion: To conclude, roasted hazelnut is more prone to gastric digestion than raw, and cause milder IgE response in patients. Gastric phase digestion of raw and roasted hazelnut kernels results in partial extraction and digestion of Cor a 11 and Cor a 9 into digestion- resistant peptides with preserved IgE-binding epitopes. These results demonstrate substantial resistance of raw and roasted hazelnut allergens to gastric digestion since they remained mostly intact after 2 h of gastric (pepsin) digestion and retained their allergenicity.

AB  - Introduction. Peanut allergy affects a large portion of world population causing reactions ranging from mild to severe. Major peanut allergen IgE epitopes are well characterized but little is known about their post-translational modifications (PTM) and how they are affected by thermal treatment. PTM profile may differ between raw and thermally treated peanut, which could affect its allergic potential depending on type, size and position of modifications.
Objective. Our aim was to analyse and compare PTM profiles of 4 major peanut allergens - Ara h 1, Ara h 2, Ara h 3 and Ara h 6, as well as their amounts in raw and roasted samples using bottom-up proteomics methods.
Methodology. Full peanut protein extracts (both thermally treated and non-treated) were digested in gel and in solution, and analysed by a Top10 nLC-MS/MS method by LTQ Orbitrap XL (Thermo Fisher Scientific Inc., Germany). Within the extracts major allergens - Ara h 1, Ara h 2, Ara h 3 and Ara h 6 were identified, label free quantified (LFQ) and searched for PTMs by Peaks X software (Bioinformatics solutions Inc.I, Canada). Epitope sequences were acquired from the Immune Epitope Database (IEDB www.iedb.org).
Main findings. LFQ results show that there is no significant change in the amounts of any of the studied allergens between raw and roasted extracts. Out of the 4 allergens Ara h 6 is modified in the highest portion, with respect to the protein size: 15% and 12% of its positions are modified in raw and roasted sample, respectively. Total of 21 modifications were quantified between the two preparations, with oxidation (M), methylation (K,R) and dethiomethylation affecting the largest number of peptides.
Conclusions. Peanut allergen epitopes are indeed carriers of PTMs that differ in pattern and quantity between treated and non-treated extracts. The in silico discovered PTMs could affect protein digestibility and allergenicity. Further investigation is necessary in order to fully understand the impact protein modifications could have on their allergenic potential.

AB  - Alergija na hranu je reakcija preosetljivosti imunskog sistema na hranu koja dovodi dostvaranja IgE antitela. Ne postoji efikasan tretman i izbegavanje namirnica koje izazivajusimptome je jedini način za sprečavanje ozbiljnih posledica. Cilj ove teze je izučavanjeposttranslacionih i hemijskih modifikacija (PTM i HM) i interakcija alergena hrane sabiološki aktivnim polifenolom biljnog porekla.Alergija na crveno meso je novootkriveni tip odložene reakcije, sa PTM galaktozil-α-1,3-galaktozom (α-Gal) kao epitopom. Ispitani su podložnost model proteina - tiroglobulina(TG) digestiji pepsinom, prisustvo α-Gal na rezultujućim peptidima i pretpostavljenomesto vezivanja α-Gal za TG. Pokazano je da je α-Gal celim tokom simulirane želudačnedigestije vezan za nastale peptide TG, koji zadržavaju sposobnost da vežu IgE.Alergija na kikiriki je među najopasnijim zbog učestalosti, postojanosti i ozbiljnostisimptoma. Postoje razlike u alergenosti između sirovog i pečenog kikirikija, koje mogupoticati od razlika u modifikacijama alergena.

AB  - Food allergy is an immune system reaction to certain foods that results in IgE antibodygeneration. Efficient treatment does not exist, so avoidance of trigger foods is the onlyway to prevent serious consequences. The aim of this thesis was to study posttranslationaland chemical modifications (PTM and CM) of food allergens and their interactions withbiologically active plant polyphenol.Red meat allergy is a newly discovered type of allergy with delayed symptoms and aPTM - galactose-α-1,3-galactose (α-Gal) as an epitope. Digestibility of a model protein -thyroglobulin (TG) by pepsin and presence of α-Gal on resulting peptides was studied,and the position of α-Gal containing glycan on TG was proposed. It was shown thatthroughout simulated gastric digestion α-Gal remains bound to IgE reactive TG peptides.Peanut allergy is among most dangerous types of food allergies due to prevalence,persistence and symptom severity. Differences in allergenicity between raw and roastedpeanuts were previously shown and might stem from differences in protein modifications.Differences in major allergen modifications between raw and roasted peanut werestudied. Twenty-seven modifications were detected, 4 of which exclusively on allergensfrom roasted peanuts. Differences in modification profiling were found between the twoprotein preparations that can affect their allergenicity.Peanut 2S albumins are compact digestion-resistant proteins, which attributes to theirallergenicity. Their interactions with epigallocatechin-3-gallate (EGCG), animmunomodulatory green tea catechin that facilitates pepsin digestion of proteins werestudied. The results show that binding of EGCG to these allergens induces conformationalchanges, and is enthalpy favorable with binding constants of 104 M-1.

AB  - Background: Sensitization to non-specific lipid transfer protein (ns-LTPs) in plant foods is regarded as a risk factor for generalized allergic reactions. Stability to gastric digestion represents very important parameter of food proteins allergenicity. Usually studies of digestion were carried out on purified proteins, but has never been examined the influence of different food matrices on different allergens. Allergens from the nsLTP family are known to share a characteristic structure which is highly resistant to proteolysis, and therefore, IgE cross-reactivity of nsLTPs needs to be investigated in the environment such as complex food matrix.
Objective: The aim of this research project is to reveal how proteins are digested (by Minekus protocol) within the natural food matrix and possible consequences on their allergenicity, with the special focus on ns-LTP.
Methods: Pure nsLTPs from walnut were labelled with Alexa 633 and added to whole grain of grounded raw walnuts, incubated with human α-amylase, and pepsin, therefore mimicking the effects of oral and gastric digestion, in total duration of 2h. Proteins extracted from the mixture were analyzed by one-dimensional (1D) and two-dimensional SDS-PAGe, and respective 1D and 2D immunoblots.
Results: Most proteins from pepsin digested walnut sample were more resistant to digestion according to 1D SDS PAGE. Pepsin digested raw walnut sample with nsLTP were assessed by 2D PAGE to compare profiles of the digested and control sample (no pepsin added). 2D SDSPAGE of digested and control walnut samples showed almost identical profiles, especially in the context of fluorescently labelled nsLTP allergens. These results demonstrate substantial resistance of nsLTP allergens to gastric digestion since they remained mostly intact after 2 h of gastric (pepsin) digestion.
Conclusion: Further research is needed to be able to grade stability/resistance of selected food allergens to gastric digestion as a consequence of food matrix modulating effects. We propose that certain combinations of foods and allergens could provide additional protection or on the contrary ease the digestion, by comparing trends between control and digested samples and between different digested combinations as well.

digestion, and they sensitize individual via the gastrointestinal tract. Mikenus et al. published a
standardized static digestion method for food, based on physiological conditions emphasizing the
impact of food matrices. Immunoreactive proteins (large fragments) and peptides (short digestion
resistant peptides SDRPs; <10 kDa), to which the immune system of the gastrointestinal tract is
exposed during digestion of peanut proteins, has not been investigated under pure physiological
conditions suggested by this protocol.
Matherial and methods: Whole grain of grounded raw peanut was incubated with human α-
amylase, and pepsin, mimicking the effects of oral and gastric digestion, in total duration of 2h.
Bottom up proteomic approach, immunoblotting with allergen-specific antibodies from peanut-
sensitized patients, enzyme-linked immunosorbent inhibition assay and ImmunoCAP tests, were
used to identify and characterize peanut digesta.
Results: After 2h of oral/gastric phase we got, intact proteins, large, digestion resistant peptides
(DRP) and SDRPs, as well. Ara h 2 and Ara h 6 remained mostly intact, and short DRPs from Ara h
2 and Ara h 6 were more potent in inhibiting IgE binding than Ara h 1 and Ara 3. Ara h 1 and Ara h
3 showed preserved allergenic capacity, as well. Almost all of identified short DRPs from Ara h 1,
Ara h 2 and Ara h 3, with preserved allergenic potential, were constituents of continuous epitope
sequences found via Immune Epitope Database (www.iedb.org).
Conclusion: Processes of protein extraction from the matrix and their enzymatic digestion occur
simultaneously. Oral and gastric phase digestion products of raw peanut are intact proteins, large

AB  - Objective: Haliotis discus (Japanese abalone), mollusks among various shellfish, is a highly
nutritive food resource in the world, but also among the eight allergic food groups accounting for
approximately 90% of all immunoglobulin E food allergies worldwide. The general objective of our
research is to comprehensively investigate stability and structures of pepsin-resistant allergens, of
their larger fragments, and of short digestion resistant peptides (SDRPs) released by pepsin
digestion of whole raw and extract of shellfish, under standardized and physiologically relevant
gastric conditions.
Materials and Methods: Extract of raw whole shellfish (eRSS) and whole raw shellfish (wRSS),
were pepsin digested according to standardized static digestion protocol. Controls were treated in a
same manner without adding pepsin. Supernatant of samples and its counterpart controls were
precipitated with TCA/acetone. Obtained proteins were assessed by 2D SDS PAGE and 1D SDS-
PAGE, under reducing and non-reducing conditions. 1D SDS-PAGE of RSS were analyzed by
ncLC-MS/MS (Orbitrap LTQ) shot-gun proteomics. Relative quantification was performed by LFQ
algorithm within Peaks 8.5 software package Bioinformatics Solutions Inc. (BSI), Waterloo,
Canada.
Results and Conclusion: 1D SDS-PAGE analysis of eRSS and wRSS, and its controls showed a
range of proteins in varied concentrations between 10-250 kDa. In extracted and whole raw
shellfish, approximately 22 prominent protein bands were observed including the distinct bands
corresponding with the molecular weights of recognized shellfish allergen, tropomyosin (37-
39kDa). Fewer high molecular weight proteins were observed followed by protein smearing,
specifically around the low molecular weight protein bands. The smearing could possibly be due to
the breakdown products and the glycation. There were slight differences between the protein
profiles under reducing and non-reducing conditions as well. Nevertheless, there was the retention
of a band in the 37kDa molecular weight marker in all 4 samples, likely consistent with heat stable
tropomyosin (TM). Mass spectrometry showed allergens that are characterized (Hal d 1 and Hal di
1), with 90% of sequence homology with main tropomyosin allergens from seafood.
Scientific impact and relevance: The results will highlight effects of food matrix on shellfish
allergens digestibility proving its relevancy in molecular allergology. Moreover, an insight will be
obtained on the differences in digestibility of allergenic versus non-allergenic tropomyosins in the
real food matrix.

ncLC-MS/MS (Orbitrap LTQ) shot-gun proteomics. Relative quantification was performed by LFQ
algorithm within Peaks 8.5 software package Bioinformatics Solutions Inc. (BSI), Waterloo,
Canada.
Results and Conclusion: 1D SDS-PAGE analysis of eRSS and wRSS, and its controls showed a
range of proteins in varied concentrations between 10-250 kDa. In extracted and whole raw
shellfish, approximately 22 prominent protein bands were observed including the distinct bands
corresponding with the molecular weights of recognized shellfish allergen, tropomyosin (37-
39kDa). Fewer high molecular weight proteins were observed followed by protein smearing,
specifically around the low molecular weight protein bands. The smearing could possibly be due to
the breakdown products and the glycation. There were slight differences between the protein
profiles under reducing and non-reducing conditions as well. Nevertheless, there was the retention
of a band in the 37kDa molecular weight marker in all 4 samples, likely consistent with heat stable
tropomyosin (TM). Mass spectrometry showed allergens that are characterized (Hal d 1 and Hal di
1), with 90% of sequence homology with main tropomyosin allergens from seafood.
Scientific impact and relevance: The results will highlight effects of food matrix on shellfish
allergens digestibility proving its relevancy in molecular allergology. Moreover, an insight will be
obtained on the differences in digestibility of allergenic versus non-allergenic tropomyosins in the
real food matrix.",

AB  - Peanut allergy affects a large portion of world population causing reactions ranging from
mild to severe. Seed storage proteins Ara h 1, Ara h 2, Ara h 3 and Ara h 6 are peanut
allergens, with well characterized IgE epitopes but little is known about PTMs effect on their
properties. Our aim was to investigate PTMs present on known epitopes of said purified
proteins using bottom-up proteomcs methods.
Out of the 4 allergens, Ara h 2 has the highest number of PTMs (14), while the most common
are hydroxylation Pro, dehydration and deamidation (N, Q). Peanut allergen epitopes are
indeed carriers of PTMs that could affect protein allergenicity and digestibility. Further
investigation on peanut extracts prepared in different ways is necessary in order to fully
understand the impact protein modifications could have on their allergenic potential.
