1,2 dihydrovomilenine reductase

In enzymology, a 1,2-dihydrovomilenine reductase (EC 1.3.1.73) 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.
