4-hydroxybenzoate 3-monooxygenase [NAD(P)H];
4-hydroxybenzoate 3-monooxygenase (reduced nicotinamide adenine dinucleotide (phosphate));
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
4-hydroxybenzoate,NAD(P)H:oxygen oxidoreductase (3-hydroxylating)
4-hydroxybenzoate + NAD(P)H + H+ + O2 = 3,4-dihydroxybenzoate + NAD(P)+ + H2O [RN:
A flavoprotein (FAD). The enzyme from Corynebacterium cyclohexanicum is highly specific for 4-hydroxybenzoate, but uses NADH and NADPH at approximately equal rates (cf. EC
4-hydroxybenzoate 3-monooxygenase). It is less specific for NADPH than EC
