| tryptophan 7-halogenase M-CSA #977 | Tryptophan 7-halogenase catalyses the chlorination of free tryptophan to 7-chlorotryptophan, which is the first step in the synthesis of the antibiotic pyrrolnitrin. Enzyme-catalysed chlorination of organic compounds in the laboratory remains a challenge, thus understanding the reaction mechanism of tryptophan 7-halogenase is important. | EC: 1.14.19.9 (UniProt) |
