AB  - Banana allergy is often associated with the pollen and latex allergies, which led us to the  hypothesis that some yet unidentified banana allergen could provide a basis of the latex-pollen-fruit syndrome. S-adenosyl-L-homocysteine hydrolase (SAHH) was recently identified in the literature as a novel plant allergen. This study aimed to assess the allergenic potential of the naturally occurring banana SAHH (nSAHH) and its recombinant homolog produced in E. coli (rSAHH). nSAHH showed IgE reactivity with a serum pool of twelve banana-allergic persons,
while rSAHH displayed IgE reactivity in ten out of the twelve tested patients. Five linear B-cell epitopes were identified on the rSAHH surface, exhibiting ≥ 90 % sequence homology with relevant plant SAHH allergens. Our findings have elucidated SAHH as a novel plant panallergen, underlying the cross-reactivity between plant derived food and respiratory allergens, confirming our initial hypothesis.

AB  - Ovalbumin (OVA) is the most abundant egg white protein. It is a globular, acidic phosphorylated glycoprotein of the serpin family with a molecular weight of 45 kDa. OVA is rich in essential amino acids and upon proteolytic digestion yields bioactive peptides (BAPs), recognized nutraceuticals with hypotensive, antimicrobial, antioxidant, and anticancer properties that contribute to the overall nutritional and health benefits of eggs. OVA is a common choice in the food, biomedical, and pharmaceutical industries due to its useful properties during food processing, capacity to form biocompatible gels, and special properties as an effective transporter for a variety of nutraceuticals and pharmaceuticals. Cellular agriculture is an innovative interdisciplinary approach that bypasses conventional animal husbandry in the production of animal proteins. OVA expressed in Trichoderma reesei (T. reesei) most closely mimics the structural and functional properties of its natural homolog and is therefore considered a sustainable alternative to chicken egg white protein powder.
Egg allergy poses serious concerns for food safety and an important socioeconomic burden to the food sector and public health. OVA has been extensively studied as an important egg allergen in mice and in vitro experimental models, providing fundamental insights into the molecular mechanisms of allergy and identifying new therapeutic targets. This chapter focuses on providing a comprehensive overview of the state-of-the-art of OVA in human nutrition and the food industry. After presenting the structure underlying the functional properties of OVA, we provide a critical perspective on cellular agriculture as a non-poultry production of OVA. Additionally, the detailed nutritional and biotechnological significance of OVA is elaborated. The final part of this chapter provides a comprehensive insight into OVA as a model antigen and food allergen from a food safety perspective.

AB  - The surface of microorganisms is covered with carbohydrates, which makes them unique, self-sustaining glycan probes. Lectins are able to bind to these probes, and this interaction can be exploited for selecting microorganisms or novel lectins. To examine lectin-microorganism interactions, we have previously developed an enzyme-linked lectin sorbent assay (ELLSA) with whole bacterial cells. To further test the validity of this methodology, here we compare it with flow cytometry. For this purpose, we used biotinylated recombinantly produced lectin from Musa acuminata (BanLec), this lectin’s recombinantly produced chimera with green fluorescent protein (BanLec-eGFP) and a lectin from Ricinus communis (RCA120), both biotinylated and FITC labeled. Parallel testing showed equivalent results for the two methods, in terms of the presence or absence of binding, with signal intensity yielding high Pearson correlation coefficient of 0.8 for BanLec and 0.95 for RCA120. The ELLSA method demonstrated multiple advantages, such as reliability and convenience for high-throughput analysis; it also required less lectin and yielded more consistent results. As such, ELLSA proved to be a useful tool for profiling microbial glycan structures or testing novel lectins.

AB  - Diagnostic evaluation of specific antibodies against the SARS-CoV-2 virus is mainly based on spike (S) and nucleocapsid (N) proteins. Despite the critical functions in virus infection and contribution to the pattern of immunodominance in COVID-19, exploitation of the most abundant membrane (M) protein in the SARS-CoV-2 serology tests is minimal. This study investigated the recombinant M protein’s immunoreactivity with the sera from COVID-19 convalescents. In silico designed protein was created from the outer N-terminal part (19 aa) and internal C-terminal tail (101–222 aa) of the M protein (YP_009724393.1) and was recombinantly produced and purified. The designed M protein (16,498.74 Da, pI 8.79) revealed both IgM and IgG reactivity with serum samples from COVID-19 convalescents in Western blot. In ELISA, more than 93% (28/30) of COVID-19 sera were positive for IgM detection, and more than 96% (29/30) were positive for specific IgG detection to M protein. Based on the capacity to provoke an immune response and its strong antigenic properties, as shown here, and the fact that it is also involved in the virion entry into host cells, the M protein of the SARS-CoV-2 virus as a good antigen has the potential in diagnostic purposes and vaccine design.

AB  - Fluorescently labeled lectins are useful tools for in vivo and in vitro studies of the structure and function of tissues and various pathogens such as viruses, bacteria, and fungi. For the evaluation of high-mannose glycans present on various glycoproteins, a three-dimensional (3D) model of the chimera was designed from the crystal structures of recombinant banana lectin (BanLec, Protein Data Bank entry (PDB): 5EXG) and an enhanced green fluorescent protein (eGFP, PDB 4EUL) by applying molecular modeling and molecular mechanics and expressed in Escherichia coli. BanLec-eGFP, produced as a soluble cytosolic protein of about 42 kDa, revealed β-sheets (41%) as the predominant secondary structures, with the emission peak maximum detected at 509 nm (excitation wavelength 488 nm). More than 65% of the primary structure was confirmed by mass spectrometry. Competitive BanLec-eGFP binding to high mannose glycans of the influenza vaccine (Vaxigrip®) was shown in a fluorescence-linked lectin sorbent assay (FLLSA) with monosaccharides (mannose and glucose) and wild type BanLec and H84T BanLec mutant. BanLec-eGFP exhibited binding to mannose residues on different strains of Salmonella in flow cytometry, with especially pronounced binding to a Salmonella Typhi clinical isolate. BanLec-eGFP can be a useful tool for screening high-mannose glycosylation sites on different microorganisms.
