4-Nitrophenol 4-monooxygenase

4-nitrophenol 4-monooxygenase (, pnpA (gene), pdcA (gene)) is an enzyme with systematic name 4-nitrophenol,NAD(P)H:oxygen 4-oxidoreductase (4-hydroxylating, nitrite-forming). This enzyme catalyses the following chemical reaction


 * 4-nitrophenol + NADPH + H+ + O2 $$\rightleftharpoons$$ 1,4-benzoquinone + nitrite + NADP+ + H2O

4-nitrophenol 4-monooxygenase contains FAD.
