Function

TRP6H_STRAO Involved in the biosynthesis of thienodolin, a plant growth-regulating compound (PubMed:24692213). Catalyzes the chlorination of tryptophan (Trp) at C6 position to yield 6-chloro-tryptophan (PubMed:24692213, PubMed:33465708). It is also able to use bromide ions to generate monobrominated Trp (PubMed:33465708, PubMed:36259362). In vitro, accepts a wide range of amides and peptides carrying either L- or D-Trp at the N-terminus (PubMed:36259362).^{[1] [2] [3]}
