RT "The complete amino-acid sequence of the endogenous alpha-amylase inhibitor
RT in wheat.";
RL Biochim. Biophys. Acta 871:250-256(1986).
CC -!- FUNCTION: Inhibitor of endogenous alpha-amylase (wheat also produces an
CC exogenous inhibitor which inactivates alpha-amylase from animal and
CC insect origin). This inhibitor can also inhibit subtilisin.
CC -!- SIMILARITY: Belongs to the protease inhibitor I3 (leguminous Kunitz-
CC type inhibitor) family. {ECO:0000305}.
