Thus, the two substrates of this enzyme are (6S,9R)-6-hydroxy-3-oxo-alpha-ionol and NAD+, whereas its 3 products are (6R)-6-hydroxy-3-oxo-alpha-ionone, NADH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is vomifoliol:NAD+ oxidoreductase. Other names in common use include vomifoliol 4'-dehydrogenase, and vomifoliol:NAD+ 4'-oxidoreductase.
