- vestitone + NADP+ 2'-hydroxyformononetin + NADPH + H+
Thus, the two substrates of this enzyme are vestitone and NADP+, whereas its 3 products are 2'-hydroxyformononetin, 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 vestitone:NADP+ oxidoreductase. Other names in common use include NADPH:2'-hydroxyisoflavone oxidoreductase, isoflavone reductase, and 2',7-dihydroxy-4',5'-methylenedioxyisoflavone reductase.
