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.
