alpha-Amylases catalyze the hydrolysis of alpha-D-(1,4)-glucan linkages in starch and related compounds. There is a wide range of industrial and medical applications for these enzymes and their inhibitors. The Ragi bifunctional alpha-amylase/trypsin inhibitor (RBI) is the prototype of the cereal inhibitor superfamily and is the only member of this family that inhibits both trypsin and alpha-amylases. The mode of inhibition of alpha-amylases by these cereal inhibitors has so far been unknown.
