In enzymology a 5-O-(4-coumaroyl)-D-quinate 3′-monooxygenase (EC 1.14.13.36) is an enzyme that catalyzes the chemical reactiontrans-5-O-(4-coumaroyl)-D-quinate + NADPH + H+ + O2 trans-5-O-caffeoyl-D-quinate + NADP+ + H2OThe 4 substrates of this enzyme are trans-5-O-(4-coumaroyl)-D-quinate NADPH H+ and O2 whereas its 3 products are trans-5-O-caffeoyl-D-quinate 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.
