| Comment(s) |
|---|
- The enzyme, characterized from a number of bacterial species,
participates in the degradation of 3,5,6-trichloropyridin-2-ol (TCP),
a metabolite of the common organophosphorus insecticide chlorpyrifos.
- The enzyme is a multifunctional flavin-dependent monooxygenase that
displaces three chlorine atoms by attacking three different positions
in the substrate.
- Each reaction catalyzed by the enzyme displaces a single chlorine and
results in formation of a dione, which must be reduced by FADH2
before the monooxygenase could catalyze the next step.
- The large amount of FADH2 that is required is generated by a
dedicated flavin reductase (TcpX). cf. EC 1.14.14.173.
