| - | + | [https://www.uniprot.org/uniprot/REBH_LENAE REBH_LENAE] Involved in the biosynthesis of the indolocarbazole antitumor agent rebeccamycin. Catalyzes the chlorination of tryptophan (Trp) at C7 position to yield 7-chlorotryptophan. The reaction between FADH2, Cl-, and O2 generates the powerful oxidant HOCl, which is presumed to carry out the chlorination reaction. The reaction of HOCl with the active site Lys-79 generates a lysine chloramine, which plays a key role in directing regiospecific chlorination of substrate in this important class of biosynthetic enzymes. It is also able to use bromide ions to generate monobrominated Trp.<ref>PMID:11983340</ref> <ref>PMID:15743914</ref> <ref>PMID:17260957</ref> | |
