ID 1.3.3.10 DE tryptophan alpha,beta-oxidase. AN L-tryptophan 2',3'-oxidase. AN L-tryptophan alpha,beta-dehydrogenase. CA L-tryptophan + O2 = alpha,beta-didehydrotryptophan + H2O2. CC -!- The enzyme from Chromobacterium violaceum is specific for tryptophan CC derivatives possessing its carboxyl group free or as an amide or CC ester, and an unsubstituted indole ring. CC -!- Also catalyzes the alpha,beta dehydrogenation of L-tryptophan side CC chains in peptides. CC -!- The product of the reaction can hydrolyze spontaneously to form CC indolepyruvate. CC -!- Formerly EC 1.4.3.17. //
