Function
function
Involved in lignin biosynthesis. Catalyzes the final step specific for the production of lignin monomers. Catalyzes the NADPH-dependent reduction of coniferaldehyde, 5-hydroxyconiferaldehyde, sinapaldehyde, 4-coumaraldehyde and caffeyl aldehyde to their respective alcohols.
Catalytic activity
- (E)-cinnamyl alcohol + NADP+ = (E)-cinnamaldehyde + NADPH + H+This reaction proceeds in the backward direction.
- (E)-caffeyl alcohol + NADP+ = (E)-caffeyl aldehyde + NADPH + H+This reaction proceeds in the backward direction.
Cofactor
Note: Binds 2 Zn2+ ions per subunit.
Pathway
Aromatic compound metabolism; phenylpropanoid biosynthesis.
