Legumin, or vegetable casein, is a protein substance analogous to the casein of milk, obtained from beans, peas, lentils, vetches and other leguminous seeds. It is a member of the globulin group.
Properties
Karl Heinrich Ritthausen found legumin from peas, vetches, lentils, and field beans to contain the elements in the following proportions: carbon, 51.48%; hydrogen, 7.02%; nitrogen, 16.77%; and oxygen, 24.32%. Legumin is soluble in water,and is soluble in very weak acids and alkalies; and it is not coagulated by heat.
It resembles the casein of mammalian milk, with which it was considered identical by Liebig and others, and was therefore called “vegetable casein.” It contains less carbon and more nitrogen, however, than true casein. Upon treatment with sulphuric acid, legumin gives leucin, tyrosin, and glutamic and aspartic acids.

- In search of markers for somatic embryo maturation in hybrid larch (Larix × eurolepis): global DNA methylation and proteomic analyses.
- Teyssier C1, Maury S, Beaufour M, Grondin C, Delaunay A, Le Metté C, Ader K, Cadene M, Label P, Lelu-Walter MA.Author information 1INRA, UR 0588, Research Unit for Breeding, Genetics and Physiology of Forest Trees, Orléans, F-45075, France.AbstractA global DNA methylation and proteomics approach was used to investigate somatic embryo maturation in hybrid larch. Each developmental step during somatic embryogenesis was associated with a distinct and significantly different global DNA methylation level: from 45.8% mC for undifferentiated somatic embryos (1-week proliferation) to 61.5% mC for immature somatic embryos (1-week maturation), while maturation was associated with a decrease in DNA methylation to 53.4% for mature cotyledonary somatic embryos (8-weeks maturation). The presence of 5-azacytidine (hypo-methylating agent) or hydroxyurea (hyper-methylating agent) in the maturation medium altered the global DNA methylation status of the embryogenic cultures, and significantly reduced both their relative growth rate and embryogenic potential, suggesting an important role for DNA methylation in embryogenesis. Maturation was also assessed by examining changes in the total protein profile. Storage proteins, identified as legumin- and vicilin-like, appeared at the precotyledonary stage. In the proteomic study, total soluble proteins were extracted from embryos after 1 and 8 weeks of maturation, and separated by two-dimensional gel electrophoresis. There were 147 spots which showed significant differences between the stages of maturation; they were found to be involved mainly in primary metabolism and the stabilization of the resulting metabolites. This indicated that the somatic embryo was still metabolically active at 8 weeks of maturation. This is the first report of analyses of global DNA methylation (including the effects of hyper- and hypo-treatments) and proteome during somatic embryogenesis in hybrid larch, and thus provides novel insights into maturation of conifer somatic embryos.

- Tobacco seeds expressing feedback-insensitive cystathionine gamma-synthase exhibit elevated content of methionine and altered primary metabolic profile.

In this study, we aimed to elucidate the regulatory role of the first committed enzyme in the methionine biosynthesis pathway, cystathionine γ-synthase (CGS), on methionine accumulation in tobacco seeds. We also studied the effect of this manipulation on the seed's metabolism.

- Conformational epitope mapping of Pru du 6, a major allergen from almond nut.
- Willison LN1, Zhang Q, Su M, Teuber SS, Sathe SK, Roux KH.Author information 1Department of Biological Science, Florida State University, Tallahassee, FL, USA.AbstractTree nuts are a widely consumed food. Although enjoyed safely by most individuals, allergic reactions to tree nuts, including almond, are not uncommon. Almond prunin (Pru du 6), an 11S globulin (legumin), is an abundant nut seed protein and a major allergen. Conformational epitope mapping studies of prunin have been performed with a murine monoclonal antibody (mAb) 4C10. This mAb reacts with non-reduced but not reduced prunin in immunoblotting assays, indicating the recognition of a conformational epitope. 4C10 competes with patient IgE, as assessed by ELISA, indicating clinical significance of the epitope. To characterize the 4C10 epitope, hydrogen/deuterium exchange (HDX) monitored by 14.5 T Fourier transform ion cyclotron resonance mass spectrometry (MS) was performed on the native prunin-4C10 complex and on uncomplexed native prunin. Several epitope candidate peptides that differ in deuterium uptake between the complexed and uncomplexed forms were identified. The epitope was further mapped by analyzing chimeric molecules incorporating segments of the homologous soybean allergen, Gly m 6, in immunoassays. These data indicate that the 4C10 epitope overlaps with a subset of patient IgE binding epitopes on almond prunin and further supports HDX-MS as a valid technique for mapping conformational epitopes.
