Tryptophan 5-halogenase PyrH

UniProtKB accession:  A4D0H5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the biosynthesis of the antibiotic compound pyrroindomycin B (PubMed:15850981). Catalyzes the chlorination of tryptophan (Trp) at C5 position to yield 5-chloro-L-tryptophan (PubMed:15850981, PubMed:33465708). It is also able to use bromide ions to generate monobrominated Trp, but the brominating activity is only about 75% of the chlorinating activity (PubMed:15850981).
