CC -!- FUNCTION: Involved in lignin biosynthesis. Catalyzes the final step
CC specific for the production of lignin monomers. Catalyzes the NADPH-
CC dependent reduction of coniferaldehyde, 5-hydroxyconiferaldehyde,
CC sinapaldehyde, 4-coumaraldehyde and caffeyl aldehyde to their
CC respective alcohols. {ECO:0000250|UniProtKB:O49482}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(E)-cinnamyl alcohol + NADP(+) = (E)-cinnamaldehyde + H(+) +
CC NADPH; Xref=Rhea:RHEA:10392, ChEBI:CHEBI:15378, ChEBI:CHEBI:16731,
CC ChEBI:CHEBI:33227, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349;
CC EC=1.1.1.195;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:O49482};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000250|UniProtKB:O49482};
CC -!- PATHWAY: Aromatic compound metabolism; phenylpropanoid biosynthesis.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:O49482}.
CC -!- SIMILARITY: Belongs to the zinc-containing alcohol dehydrogenase
CC family. {ECO:0000305}.
