Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
An FAD-dependent halogenase. The enzyme, characterized from the bacterium Kutzneria sp. 744, works in tandem with EC 1.14.19.9, tryptophan 7-halogenase, (ktzQ) to generate 6,7-dichloro-L-tryptophan, which is incorporated as a pyrroloindoline in the kutznerides family of natural products. It has a 120-fold preference for 7-chloro-L-tryptophan over L-tryptophan as substrate.
