In enzymology, a 1,2-dihydrovomilenine reductase (EC 18.104.22.168) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are 17-O-acetylnorajmaline and NADP+, whereas its 3 products are 1,2-dihydrovomilenine, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 17-O-acetylnorajmaline:NADP+ oxidoreductase. This enzyme participates in indole and ipecac alkaloid biosynthesis.
