RT   "Structures of heat-stable and unstable homologues of the sweet protein
RT   mabinlin. The difference in the heat stability is due to replacement of a
RT   single amino acid residue.";
RL   Eur. J. Biochem. 223:989-995(1994).
CC   -!- FUNCTION: 2S seed storage protein having sweetness-inducing activity.
CC       This form is not heat stable.
CC   -!- SUBUNIT: Heterodimer of a small A and a large B chain linked by
CC       disulfide bonds.
CC   -!- SIMILARITY: Belongs to the 2S seed storage albumins family.
CC       {ECO:0000305}.
