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  - The accurate diagnosis of people with suspected infection with the SARS-CoV-2 is
essential to curb the global spread of COVID-19. The presence of SARS-CoV-2 can be
detected by RT-PCR (it detects RNA of the virus) or by the presence of viral antigens in
biological fluids in ELISA or similar techniques using antibodies developed in animals.
The aim of the study was the establishment of a quantitative polyclonal sera-based test for
routine measurement of the concentration of SARS CoV-2 nucleocapsid protein using
absorbance measurement in a standard 96-well microtiter plate. For the purposes of the test
development, recombinant N protein was produced and used for the production of mice
and rabbit antisera. Produced antisera were purified and titer was determined. High-affinity
polyclonal N-protein specific antisera were used for N-protein specific ELISA test
development. The test is based on mice polyclonal sera adhered to microtiter plate bottom
for the capture of the N protein from the specimen. Various concentrations of the
recombinant N-protein were used to generate a standard curve for protein quantification.
The N-protein bound to the mice antibodies was detected with rabbit polyclonal sera and
anti-rabbit antibody coupled to an enzyme that provides spectrophotometric measurement.
We have successfully developed the prototype ELISA for the quantification of N-protein
with the detection limit being in the range of ng/mL. The average LOD value for the
prototype ELISA was determined to be 9.2 ng/mL, while the average LOQ value was
10.2 ng/mL. We have demonstrated that produced polyclonal antisera are suitable for the
detection of N-protein with affinity and specificity similar to, or better than commercial
antibodies. Furthermore, the prototype ELISA can be used with satisfactory confidence for
quantification of the N-protein in protein-rich samples, similar to human sera.

AB  - β-lactoglobulin (BLG) is a major whey protein with numerous techno-functional properties desirable for the food industry. Phycocyanobilin (PCB), a bioactive pigment of Arthrospira platensis with health-promoting effects, covalently binds to BLG at physiological pH. This study investigated the effects of this covalent modification on BLG functional properties. The BLG–PCB adduct possesses enhanced antioxidant properties, and bound PCB protects BLG against free radical-induced oxidation. Despite the similar thermal stabilities of BLG and BLG–PCB, BLG–PCB is less susceptible to covalent and noncovalent aggregation under moderate heat treatment (63 °C, 30 min). Blocked thiol group and reduced hydrophobicity due to hindering of hydrophobic residues by bound PCB, as well as the heat-induced transition of β-sheet to α-helix, contributed to the low susceptibility of BLG–PCB to aggregation. BLG–PCB has a higher resistance to pepsin and pancreatin digestion than BLG and unaltered IgE-binding properties. The improved functional properties of BLG–PCB make it a useful ingredient in the food industry.

AB  - The emergence of the coronavirus SARS-CoV-2 has attracted attention of the whole scientific community. The SARS-CoV-2 spike (S) protein plays the most important role in viral attachment to host receptor angiotensin-converting enzyme 2 (ACE2), via the receptor-binding domain (RBD), fusion and entry into the host, and it serves as a target for the development of antibodies, entry inhibitors and vaccines. It has been demonstrated that phycocyanobilin (PCB), a bioactive open-chain tetrapyrrole chromophore of phycocyanin (PC), chromoprotein derived from the cyanobacterium Arthrospira platensis, can bind a plethora of different proteins, both in a noncovalent and covalent manner. This study aimed to investigate interactions of PCB with S protein and RBD respectively. Electrophoretic techniques, fluorescence spectroscopy, and inhibition of S–PCB and RBD–PCB covalent adduct formation using iodoacetamide and N-ethylmaleimide, were employed to examine interactions of PCB with S protein and RBD, while the effects of PCB binding on RBD structure were studied by CD spectroscopy. SDS-PAGE with Zn2+ staining has revealed that PCB covalently binds to both S protein and RBD, via free cysteine residues. Binding constants determined by the fluorescence quenching method were: 2.1×107 M–1 for PCB and S protein and 8.4×104 M–1 for PCB and RBD. Far-UV circular dichroism spectra showed that the binding of PCB influences RBD structure by decreasing the disordered structure content. Due to moderately strong noncovalent interactions of PCB with S protein and RBD, as well as covalent adducts formation, it may exert one of its many bioactive effects via impact on S protein binding to ACE2 receptor.

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  - Background: The world’s production of whey is estimated to be more than 200 milliontons per year. Although whey is an important source of proteins with high nutritional value andbiotechnological importance, it is still considered as a by-product of the dairy industry with loweconomic value due to low industrial exploitation. There are several challenges in the separation ofwhey proteins: low concentration, the complexity of the material and similar properties (pI, molecularmass) of some proteins.Methods: A narrative review of all the relevant papers on the present methodologies based on ionexchange and adsorption principles for isolation of whey proteins, known to the authors, was conductedResults: Traditional ion exchange techniques are widely used for the separation and purification ofthe bovine whey proteins. These methodologies, based on the anion or cation chromatographicprocedures, as well as the combination of aforementioned techniques are still preferential methodsfor the isolation of the whey proteins on the laboratory scale. However, more recent research on ionexchange membranes for this purpose has been introduced, with promising potential to be appliedon the pilot industrial scale. Newly developed methodologies based either on the ion exchangeseparation (for example: simulated moving bed chromatography, expanded bed adsorption, magneticion exchangers, etc.) or adsorption (for example: adsorption on hydroxyapatite or activatedcarbon, or molecular imprinting) are promising approaches for scaling up of the whey proteins’purification processes.Conclusion: Many procedures based on ion exchange are successfully implemented for the separationand purification of whey proteins, providing protein preparations of moderate-to-high yieldand satisfactory purity. However, the authors anticipate further development of adsorption-basedmethodologies for the separation of whey proteins by targeting the differences in proteins’ structuresrather than targeting the differences in molecular masses and pI. The complex composite multilayeredmatrices, including also inorganic components, are promising materials for simultaneousexploiting of the differences in the masses, pI and structures of whey proteins for the separation.

AB  - Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection and for assessment of immunological response after the vaccination. Nucleocapsid (N) protein is the most abundant virus protein and strong immunogen. The aim was develop efficient, low-cost production of N protein large fragment and to characterize it with bottom-up, high-resolution tandem mass spectrometry and immunologically.
SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58–419 aa) was expressed in E. coli in soluble form and purified by several chromatographic steps and was subjected to SDS-PAGE and in-gel digested with trypsin.
rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. ELISA was optimized with sera of RT-PCR confirmed positive symptomatic patients and healthy individuals. IgG detection sensitivity was 96% (47/50) and specificity 97% (67/68), while IgM detection was slightly lower. Identity of rfNP was confirmed with high scores and peptide coverage above 80%. Estimation from the value of areas under ion extracted chromatographic curves is that only up to 0,03% of the total band protein quantity belongs to host proteins, while rfNP share is well above 99,9%, resulting in highly pure nucleocapsid protein preparation.

AB  - Nucleocapsid (N) protein is the most abundant SARS-CoV-2 virus derived protein and strong immunogen which can be used as a component of the immunological tests for the diagnosis of SARS-CoV-2 infection. Recombinant fragment of N-protein (58–419 aa) was expressed in E. coli in a soluble form using developed optimized protocol of expression (16-18h, 37 °C, 0.4 mM IPTG). After lysis of cells, N-protein from soluble fraction of lysate was purified using optimized protocol for purification by immobilized metal affinity chromatography on Ni-Sepharose in two repeated steps under different elution conditions. Obtained fraction of N-protein after the second chromatography was desalted and concentrated using phosphate buffer solution and ultrafiltration. The purity of isolated N-protein was deterrmined by SDS PAGE, while high resolution mass spectrometry was used for its characterization. Isolated N-protein was over 90% purity and identified as the most intense and abundant protein fragment, with PEAKS PTM score of 508 and sequence coverage of over 70%, including 173 unique peptides.

AB  - The COVID-19 diagnostic tools are categorized into two main groups of Nucleic Acid (NA)-
based and protein-based tests. To date, nucleic acid-based detection has been announced as the
gold-standard strategy for coronavirus detection; however, protein-based tests are promising
alternatives for rapid and large-scale screening of susceptible groups. During the first months, no
rapid and reliable detecting tool was readily available to adequatly respond to the requirement of
massive testing. The aim was to develope cost-effective, sensitive and rapid screening
mechanisms for the detection of immune response to SARS-CoV2 (which causes COVID-19),
based on the principle of ELISA. The institute INEP has developed tests for detection of IgM
and IgG SARS-CoV-2 specific antibodies based on S and N proteins of virus intended to monitor
different phases of natural infection, ELISA test for IgG detection in naturale infection based on
the use of exclusively domestic components of the ELISA kit (including proteins produced in
Serbia, Faculty of Chemistry) and a test specifically designed to monitor the effects of
immunization (determination of IgG antibodies specific for the RBD domain of S protein). The
tests were independently validated at the relevant laboratories in the country and abroad, and
compared to an FDA/WHO approved tests of a major test producers. All testing for validation
was carried out on samples collected before COVID19 (negative controls), PCR confirmed
COVID19 samples (positive controls) and potencialy cross-reactive samples (other pathogens
and autoimmune diseases). The antibody tests showed high levels of sensitivity and specificity
and extremely low background noises. The kits are extremely stable, have a shelf life of 1 year
and opened kits are usable up to 3 months at storing temperatures of 5°C

AB  - Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection. Nucleocapsid (N) protein is the most abundant virus derived protein and strong immunogen. We aimed to find its efficient, low-cost production, suitable for serological diagnosis. SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58–419 aa) was expressed in E. coli in soluble form, purified by immobilized metal ion affinity chromatography and strong cation exchange chromatography after which it was analyzed by Mass and CD spectrometry and characterized biochemically and immunologically. Purified rfNP has secondary structure of full-length recombinant N protein, with high percentage of disordered structure (34.2%) and of β-sheet (40.7%). rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. ELISA was optimized with sera of RT-PCR confirmed positive symptomatic patients and healthy individuals. IgG detection sensitivity was 96% (47/50) and specificity 97% (67/68), while IgM detection was

AB  - Resveratrol is a phytoalexin produced by many plants as a defense mechanism against stress-inducing conditions. The richest dietary sources of resveratrol are berries and grapes, their juices and wines. Good bioavailability of resveratrol is not reflected in its high biological activity in vivo because of resveratrol isomerization and its poor solubility in aqueous solutions. Proteins, cyclodextrins and nanomaterials have been explored as innovative delivery vehicles for resveratrol to overcome this limitation. Numerous in vitro and in vivo studies demonstrated beneficial effects of resveratrol in cardiovascular diseases (CVD). Main beneficial effects of resveratrol intake are cardioprotective, anti-hypertensive, vasodilatory, anti-diabetic, and improvement of lipid status. As resveratrol can alleviate the numerous factors associated with CVD, it has potential as a functional supplement to reduce COVID-19 illness severity in patients displaying poor prognosis due to cardio-vascular complications. Resveratrol was shown to mitigate the major pathways involved in the pathogenesis of SARS-CoV-2 including regulation of the renin-angiotensin system and expression of angiotensin-converting enzyme 2, stimulation of immune system and downregulation of pro-inflammatory cytokine release. Therefore, several studies already have anticipated potential implementation of resveratrol in COVID-19 treatment. Regular intake of a resveratrol rich diet, or resveratrol-based complementary medicaments, may contribute to a healthier cardio-vascular system, prevention and control of CVD, including COVID-19 disease related complications of CVD.

AB  - The worldwide outbreak of COVID-19 was caused by a pathogenic virus called Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). Therapies against SARS-CoV-2 target the virus or human cells or the immune system. However, therapies based on specific antibodies, such as vaccines and monoclonal antibodies, may become inefficient enough when the virus changes its antigenicity due to mutations. Polyphenols are the major class of bioactive compounds in nature, exerting diverse health effects based on their direct antioxidant activity and their effects in the modulation of intracellular signaling. There are currently numerous clinical trials investigating the effects of polyphenols in prophylaxis and the treatment of COVID-19, from symptomatic, via moderate and severe COVID-19 treatment, to anti-fibrotic treatment in discharged COVID-19 patients. Antiviral activities of polyphenols and their impact on immune system modulation could serve as a solid basis for developing polyphenol-based natural approaches for preventing and treating COVID-19.

AB  - Demand for camel milk (CM) is increasing worldwide, due to its high nutritious value and health benefits. In this study, whole CM powders were produced by spray drying (SD) at six inlet temperatures (190 °C–250 °C) and by freeze drying (FD). Physicochemical and functional properties of CM powder proteins were investigated. SD at higher inlet temperatures (230 °C–250 °C) resulted in higher extent of Maillard reaction (MR), in comparison to lower temperatures (190 °C–200 °C) and FD treatment. Both treatments had negative effect on casein solubility, while whey proteins remained soluble and slightly increased its solubility with the extent of MR. The CM powders obtained at higher inlet temperatures demonstrated improved antioxidant activity. Secondary structure of whey proteins did not differ among the samples, while surface hydrophobicity of whey proteins was higher in all SD than in FD samples, suggesting only limited denaturation of camel whey proteins at higher inlet temperatures of drying. Thus, the effects of SD under the conditions applied in our study did not decrease camel whey protein solubility, while drying procedure itself regardless of temperature decreased solubility of camel milk caseins. MR generated during CM processing could be an important means of compensating for the lack of antioxidant protection normally associated with β-lactoglobulin but happens to be absent from this milk.

AB  - Algae have been consumed as food and medicine for centuries. Their benefits are so pronounced, due to high concentrations of vitamins, minerals, antioxidants and proteins that they are commonly referred to as superfoods. Phycocyanobilin (PCB) is a bioactive compound of microalga Spirulina platensis. It is a blue tetrapyrrole chromophore of C-phycocyanin (C-PC), the major chromoprotein of this microalga. It is covalently attached to cysteine residues of C-PC via thioether bond. The outbreak of Coronavirus Disease 2019 (COVID-19) has posed a serious threat to global public health, calling for the development of safe and effective prophylactics and therapeutics against infection of its causative agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 spike (S) protein plays the most important roles in viral attachment, fusion and entry, and it serves as a target for development of antibodies, entry inhibitors and vaccines. It mediates viral entry into host cells by first binding to a host angiotensin-converting enzyme 2 (ACE2) receptor through the receptor-binding domain (RBD) and then fusing the viral and host membranes. This study aimed to investigate interaction of bioactive PCB with S protein and RBD respectively.
Combination of electrophoretic techniques and fluorescence spectroscopy was employed in order to examine interactions of PCB and S protein, as well as interactions of PCB and RBD, while the effects of PCB binding on RBD structure were studied by CD spectroscopy.
SDS-PAGE with Zn2+ staining has revealed that PCB covalently binds to both S protein and RBD, via free cysteine residues. Binding constants determined by fluorescence quenching method were: 2.1 x 107 M–1 for PCB and S protein, and 8.4 x 104 M–1 for PCB and RBD. Far-UV circular dichroism spectra showed that PCB influences RBD structure.
Our results support the importance of further research on covalent binding of PCB to S protein and RBD and its implications. Due to its interaction with S protein and RBD, PCB may exert one of its many bioactive effects via impact on S protein binding to ACE2 receptor.

AB  - The aim of this chapter is to review and discuss methodology and protocols in the analysis of phycobiliproteins (phycocyanins, allophycocyanins, and phycoerythrins) and their chromophores. Due to the presence of multiple covalently bound open-chain tetrapyrrole chromophores, phycobiliproteins are colored and strongly fluorescent molecules, with high absorption coefficients (105 to 106) and excellent fluorescent quantum yield (0.51 up to 0.98). Therefore, a vast number of methods for phycobiliproteins analysis is based on these spectral characteristics, whereas assessment of their bioactivity is related to their exceptional redox and metal-chelating properties. This chapter is dedicated to methods used for isolation and purification, structure analysis, physicochemical properties and stability characterization, quantification, as well as in vitro and in vivo biological activities evaluation. In addition, emerging approaches related to phycobiliproteins analysis are also reviewed including interactions with other biomolecules and ions and identification of phycobiliprotein (chromo)peptides by mass spectrometry.

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 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.
