ALDH catalysis involves acylation and deacylation. During acylation, a cysteine nucleophile interacts with the carbonyl carbon of aldehyde forming a thiohemiacetal intermediate, followed by hydride transfer from a tetrahedral thiohemiacetal intermediate to the pyridine ring of NAD(P)+. Then, deacylation occurs involving hydrolysis of the resulting thioester intermediate. Glu268 and Cys296 of PcALDH are potential active site residues

metabolism
-
results suggest that PcALDHs metabolize aryl-aldehyde compounds generated during fungal degradation of lignin and various aromatic xenobiotics
metabolism
in filamentous fungi, vanillin is formed in a two-stage process in which ferulic acid is converted to vanillic acid then reduced to vanillin
