glysiinin
Glysiinin, commonly referred to as glycinin, is a major storage protein of seeds in soybeans (Glycine max) and is also found in some other legumes. It belongs to the 11S globulin family and can make up a substantial portion of seed protein. Glysiinin occurs as a hexamer composed of acidic and basic subunits derived from a single precursor polypeptide that is proteolytically cleaved into two chains linked by a disulfide bond. Multiple gene variants encode different subunits, contributing to heterogeneity in the mature complex.
During seed development, glysiinin serves as a nutrient reservoir, supplying amino acids for germination and seedling
From a nutritional perspective, glysiinin provides high-quality plant protein but may be relatively low in methionine.
Glysiinin is one of several major seed storage proteins in legumes; in soybeans it coexists with other
