CC   -!- FUNCTION: This protein found in the seeds of many leguminous and non-
CC       leguminous plants is the source of sulfur-containing amino acids in
CC       seed meals.
CC   -!- SUBUNIT: Hexamer; each subunit is composed of an acidic and a basic
CC       chain derived from a single precursor and linked by a disulfide bond.
CC   -!- SIMILARITY: Belongs to the 11S seed storage protein (globulins) family.
CC       {ECO:0000305}.
