Food allergens
Published in Richard F. Lockey, Dennis K. Ledford, Allergens and Allergen Immunotherapy, 2020
Seeds contain allergenic seed storage proteins similar to peanut and tree nuts. The 2S albumin, vicilin, and legumin proteins in sesame seeds are allergens [66]. Lupin seed, also referred to as lupini bean, is increasingly used as a protein substitute and contains allergens that extensively cross-react with other legume species, particularly peanut proteins [67]. Lentils are another legume associated with allergy. Mustard seeds also have seed storage protein allergens [14]. A seed often used in spicy food, fenugreek, cross-reacts with peanut proteins [68]. Tree nut and sesame seed oil components may also contain major allergens capable of triggering allergic reactions, depending on how the oil is processed [69].

Based on its chemical composition, Bambara groundnut has various potential uses in the pharmaceutical industry. Different types of proteins from the dried seeds have been extracted and their functions are well known. For example, 7s globulins are markers for allergic reactions, while 11s globulins are used as emulsifiers and surfactants. Also, vicilin is used in micro-particle preparation (Okpuzor et al. 2010; Nehete et al. 2013; Adebowale et al. 2011).
Molecular Analysis of Plant DNA Genomes: Conserved and Diverged DNA Sequences
Published in S. K. Dutta, DNA Systematics, 2019
The subunit genes of some plant storage proteins evolve relatively fast, therefore, comparison of the amino acid sequences of a vicilin subunit with the homological part of the phaseolin molecule has revealed 30% of homologies only;67 similar results have been obtained for lectin cDNA of Phaseolus vulgaris (cv. Tendergreen) and Pisum sativum.68

Sword bean (Canavalia gladiata) is an underutilized tropical perennial legume consumed in Asian countries. Sword bean seeds have the potential to be utilized in the manufacturing of processed foods due to their high protein and carbohydrate content (5). Canavalin, a Vicilin-class (7S) storage protein has been reported in sword bean which possess wide range of properties, especially in food processing industry (6). Bacillus subtilis fermented sword beans exhibited the presence of gallic acid, methyl gallate and ellagic acid and has shown to increase free radical scavenging and hyaluronidase inhibitory activity (7). Sword beans are excellent sources of gallotannins and their gallotannin-rich extracts can be utilized as natural antioxidant and antibacterial agents with potential health benefits as well as application in food industry (8). Lectins isolated from sword beans exhibited similarities with Concanavalin A in aminoacid composition and sequence and has been shown to have mitogenic activity in splenocytes and enhances the activity of spleen natural killer (NK) cells against YAC-1 cells (9). Sword beans serve as rich sources serine protease inhibitors (SBI-1, -2 and -3) of Bowman-Brik protease inhibitor family which have wide range of applications especially in the carcinogenesis inhibition (10). Some of the major beneficial phytochemicals that has been reported in sword beans include canavanine, canavalioside, acylated flavanol glycosides (gladiatoside A1, A2, A3, B1, B2, B3, C1 and C2), robinin, kaempferol 3-O-beta d-galactopyranosyl-7-O-alpha-l-rhamnopyranoside, kaika saponon III and polyamines (sym-homospermidine and canavalimine) (11, 12). Antioxidative potential of C. gladiata (L.) seeds extract was already demonstrated in in vitro. The sword bean seed extract can inhibit lipid peroxidation through multiple mechanisms including inactivation of scavenging free radicals, reactive oxygen species and chelation of pro oxidative transition metals (13). The antitumor potential of sword bean extract has not been explored against in vivo or in vitro tumor models till date. The present study was designed to investigate the cytotoxic and antitumor effect of edible sword bean extract against Daltons lymphoma ascites (DLA) induced ascites and solid tumors in BALB/c mice models.
