ENZYME entry: EC

Accepted Name
Tryptophan alpha,beta-oxidase.
Alternative Name(s)
L-tryptophan 2',3'-oxidase.
L-tryptophan alpha,beta-dehydrogenase.
Reaction catalysed
L-tryptophan + O(2) <=> alpha,beta-didehydrotryptophan + H(2)O(2)
  • The enzyme from Chromobacterium violaceum is specific for tryptophan derivatives possessing its carboxyl group free or as an amide or ester, and an unsubstituted indole ring.
  • Also catalyzes the alpha,beta dehydrogenation of L-tryptophan side chains in peptides.
  • The product of the reaction can hydrolyze spontaneously to form indolepyruvate.
  • Formerly EC
