ID 1.14.14.20 DE phenol 2-monooxygenase (FADH2). CA FADH2 + O2 + phenol = catechol + FAD + H(+) + H2O. CC -!- The enzyme catalyzes the ortho-hydroxylation of simple phenols into CC the corresponding catechols. CC -!- It accepts 4-methylphenol, 4-chlorophenol, and 4-fluorophenol as well CC as 4-nitrophenol, 3-nitrophenol, and resorcinol. CC -!- The enzyme is part of a two-component system that also includes an CC NADH-dependent flavin reductase. cf. EC 1.14.13.7. CC -!- It is strictly dependent on FADH2 and does not accept FMNH2. //
