ENZYME entry: EC 1.14.13.50

Accepted Name
pentachlorophenol monooxygenase.
Alternative Name(s)
PCB4MO.
PCB 4-monooxygenase.
PCP hydroxylase.
pentachlorophenol 4-monooxygenase.
pentachlorophenol dechlorinase.
pentachlorophenol dehalogenase.
pentachlorophenol hydroxylase.
Reaction catalysed
  • H(+) + NADPH + O2 + pentachlorophenol <=> 2,3,5,6-tetrachloro-1,4-benzoquinone + chloride + H2O + NADP(+)
  • 2,3,5,6-tetrachlorophenol + NADPH + O2 <=> 2,3,5,6-tetrachlorohydroquinone + H2O + NADP(+)
Comment(s)
  • The enzyme displaces a diverse range of substituents from the 4-position of polyhalogenated phenols but requires that a halogen substituent be present at the 2-position.
  • If C-4 carries a halogen substituent, reaction 1 is catalyzed; if C-4 is unsubstituted, reaction 2 is catalyzed.
