摘要：

Pentachlorophenol (PCP) hydroxylase purified from Flavobacterium sp. strain ATCC 39723 converted PCP or 2,3,5,6-tetrachlorophenol to tetrachloro-p-hydroquinone (TeCH) with the coconsumption of O2 and NADPH. The purified enzyme incorporated O-18 from O-18(2) but not from (H2O)-O-18 into the reaction end product TeCH. The results clearly demonstrate that PCP is oxidatively converted to TeCH by a monooxygenase-type enzyme from Flavobacterium sp. strain ATCC 39723.
