In enzymology a biochanin-A reductase (EC 1.3.1.46) is an enzyme that catalyzes the chemical reactiondihydrobiochanin A + NADP+ biochanin A + NADPH + H+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.
