Pentachlorophenol monooxygenase

Pentachlorophenol monooxygenase (EC 1.14.13.50, pentachlorophenol dechlorinase, pentachlorophenol dehalogenase, pentachlorophenol 4-monooxygenase, PCP hydroxylase, pentachlorophenol hydroxylase, PcpB, PCB 4-monooxygenase, PCB4MO) is an enzyme with systematic name pentachlorophenol,NADPH:oxygen oxidoreductase (hydroxylating, dechlorinating).[1][2][3][4][5] This enzyme catalyses the following chemical reaction

(1) pentachlorophenol + 2 NADPH + H+ + O2 2,3,5,6-tetrachlorohydroquinone + 2 NADP+ + chloride + H2O
(2) 2,3,5,6-tetrachlorophenol + NADPH + H+ + O2 2,3,5,6-tetrachlorohydroquinone + NADP+ + H2O
