In enzymology a trans-cinnamate 4-monooxygenase (EC 1.14.13.11) is an enzyme that catalyzes the chemical reactiontrans-cinnamate + NADPH + H+ + O2 4-hydroxycinnamate + NADP+ + H2OThe 4 substrates of this enzyme are trans-cinnamate NADPH H+ and O2 whereas its 3 products are 4-hydroxycinnamate NADP+ and H2O. This enzyme participates in phenylalanine metabolism and phenylpropanoid biosynthesis. It employs one cofactor heme.
