In enzymology a 4-hydroxyphenylacetate 3-monooxygenase (EC 1.14.14.9) is an enzyme that catalyzes the chemical reaction4-hydroxyphenylacetate + NADH + H+ + O2 34-dihydroxyphenylacetate + NAD+ + H2OThe 4 substrates of this enzyme are 4-hydroxyphenylacetate NADH H+ and O2 whereas its 3 products are 34-dihydroxyphenylacetate NAD+ 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.
