| Tryptophan + FADH(2) + chloride + O(2) + H(+) <=> 7-chloro-L-tryptophan + FAD + 2 H(2)O |
| Comment(s) |
|---|
- A flavin-dependent halogenase.
- The enzyme from the bacterium Lechevalieria aerocolonigenes catalyzes
the initial step in the biosynthesis of rebeccamycin.
- It utilizes molecular oxygen to oxidize the FADH(2) cofactor, giving
C4a-hydroperoxyflavin, which then reacts with chloride to produce a
hypochlorite ion.
- The latter reacts with an active site lysine to generate a
chloramine, which chlorinates the substrate.
- Also acts on bromide ion.
- Cf. EC 1.14.19.58 and EC 1.14.19.59.
