Accepted name: 7-chloro-L-tryptophan oxidase
Reaction: 7-chloro-L-tryptophan + O2 = 2-imino-3-(7-chloroindol-3-yl)propanoate + H2O2

Other name(s): RebO
Systematic name: 7-chloro-L-tryptophan:oxygen oxidoreductase
Comments: Contains a noncovalently bound FAD [1,2]. This enzyme catalyses a step in the biosynthesis of rebeccamycin, an indolocarbazole alkaloid produced by the bacterium Lechevalieria aerocolonigenes. During catalysis, the bound FAD is reoxidized at the expense of molecular oxygen, producing one molecule of hydrogen peroxide. The enzyme shows significant preference for 7-chloro-L-tryptophan over L-tryptophan [1].
