RT   "The legumin gene family: structure of a B type gene of Vicia faba and
RT   a possible legumin gene specific regulatory element.";

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