Thus, the two substrates of this enzyme are dihydrobiochanin A and NADP⁺, whereas its 3 products are biochanin A, 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 dihydrobiochanin-A:NADP+ Delta2-oxidoreductase. This enzyme participates in isoflavonoid biosynthesis.
