In enzymology a 4-hydroxybenzoate 3-monooxygenase (EC 1.14.13.2) is an enzyme that catalyzes the chemical reaction4-hydroxybenzoate + NADPH + H+ + O2 protocatechuate + NADP+ + H2OThe 4 substrates of this enzyme are 4-hydroxybenzoate NADPH H+ and O2 whereas its 3 products are protocatechuate NADP+ and H2O.This enzyme belongs to the family of oxidoreductases specifically those acting on paired donors with O2 as oxidant and incorporation or reduction of oxygen.
