ID 1.14.13.167 DE 4-nitrophenol 4-monooxygenase. CA 4-nitrophenol + H(+) + NADPH + O2 = 1,4-benzoquinone + H2O + NADP(+) + CA nitrite. CC -!- The enzyme catalyzes the first step in a degradation pathway for CC 4-nitrophenol, the oxidation of 4-nitrophenol at position 4 with the CC concomitant removal of the nitro group as nitrite. CC -!- The enzyme from the bacterium Pseudomonas sp. WBC-3 also catalyzes CC EC 1.14.13.166. DR C1I201, PNPA_PSEWB ; //
