In enzymology, a coniferyl-aldehyde dehydrogenase () is an enzyme that catalyzes the chemical reaction coniferyl aldehyde + H2O + NAD(P)+ ferulate + NAD(P)H + 2 H+ The 4 substrates of this enzyme are coniferyl aldehyde, H2O, NAD+, and NADP+, whereas its 4 products are ferulate, NADH, NADPH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is coniferyl aldehyde:NAD(P)+ oxidoreductase. References EC 1.2.1 NADPH-dependent enzymes NADH-dependent enzymes Enzymes of unknown structure
