EC 1.14.12.19     
Accepted name: 3-phenylpropanoate dioxygenase
Reaction: (1) 3-phenylpropanoate + NADH + H+ + O2 = 3-(cis-5,6-dihydroxycyclohexa-1,3-dien-1-yl)propanoate + NAD+
(2) (2E)-3-phenylprop-2-enoate + NADH + H+ + O2 = (2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate + NAD+

Glossary: (2E)-3-phenylprop-2-enoate = trans-cinnamate
(2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate = trans-2,3-dihydroxycinnamate
Other name(s): HcaA1A2CD; Hca dioxygenase; 3-phenylpropionate dioxygenase
Systematic name: 3-phenylpropanoate,NADH:oxygen oxidoreductase (2,3-hydroxylating)
Comments: This enzyme catalyses a step in the pathway of phenylpropanoid compounds degradation. It catalyses the insertion of both atoms of molecular oxygen into positions 2 and 3 of the phenyl ring of 3-phenylpropanoate or (2E)-3-phenylprop-2-enoate.

EC 4.1.1.102     
Accepted name: phenacrylate decarboxylase
Reaction: (1) 4-coumarate = 4-vinylphenol + CO2
(2) trans-cinnamate = styrene + CO2
(3) ferulate = 4-vinylguaiacol + CO2
Glossary: 4-coumarate = 3-(4-hydroxyphenyl)prop-2-enoate
trans-cinnamate = (2E)-3-phenylprop-2-enoate
ferulate = 4-hydroxy-3-methoxycinnamate
Other name(s): FDC1 (gene name); ferulic acid decarboxylase
Systematic name: 3-phenylprop-2-enoate carboxy-lyase
Comments: The enzyme, found in fungi, catalyses the decarboxylation of phenacrylic acids present in plant cell walls. It requires a prenylated flavin cofactor that is produced by EC 2.5.1.129, flavin prenyltransferase.
