In enzymology a flavonoid 3′-monooxygenase (EC 1.14.13.21) is an enzyme that catalyzes the chemical reactiona flavonoid + NADPH + H+ + O2 a 3′-hydroxyflavonoid + NADP+ + H2OThe 4 substrates of this enzyme are flavonoid NADPH H+ and O2 whereas its 3 products are 3′-hydroxyflavonoid 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.
