Phenol 2-monooxygenase (EC 1.14.13.7) is an enzyme that catalyzes the chemical reaction
The four substrates of this enzyme are phenol, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen and a proton. Its products are catechol, oxidised NADP+, and water.[1][2][3]
The enzyme is a flavin-containing monooxygenase that uses molecular oxygen as oxidant and incorporates one of its atoms into the starting material. The systematic name of this enzyme class is phenol,NADPH:oxygen oxidoreductase (2-hydroxylating). Other names in common use include phenol hydroxylase, and phenol o-hydroxylase. It uses flavin adenine dinucleotide as a cofactor.[4] The enzyme from Trichosporon cutaneum can hydroxylate a range of phenols.[1][5]
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1FOH, 1HQI, and 1PN0.
