Thus, the two substrates of this enzyme are L-tryptophan and O2, whereas its two products are alpha,beta-didehydrotryptophan and H2O2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with oxygen as acceptor. The systematic name of this enzyme class is L-tryptophan:oxygen alpha,beta-oxidoreductase. Other names in common use include L-tryptophan 2',3'-oxidase, and L-tryptophan alpha,beta-dehydrogenase. It employs one cofactor, heme.
