CC   -!- FUNCTION: This is a seed storage protein.
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}.
