Model of the catalytic mechanism of the L. plantarum PAD for decarboxylation of pCA [84]. The corresponding amino acids identified in B. subtilis PAD are indicated in red color [85]. The carboxyl moiety of pCA is linked to residues Tyr18 and Tyr20 in this enzyme. Deprotonation of the hydroxyl group of pCA by residue Glu71 (first step) leads to the formation of a semi-quinone intermediate whose decarboxylation generates 4-vinylphenol (second step)
