Abstract

Oxidation of the bifunctional wheat inhibitor of subtilisin and endogenous alpha-amylase catalyzed by horseradish peroxidase results in theloss of the inhibitory activity against both enzymes. The enzymatic oxidation is accompanied by modification of one methionine and two tryptophan residues in the protein. The results obtained, together with data on chemical modification and limited proteolysis, allow us to conclude that Met34-Ala35 is the reactive site of the inhibitor responsiblefor the interaction with subtilisin. It is supposed that the reactivesite of the inhibitor responsible for the interaction with alpha-amylase contains one or two tryptophan residues.
