Biochanin-A reductase

In enzymology, biochanin-A reductase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are biochanin A, reduced nicotinamide adenine dinucleotide phosphate, and a proton. Its products are 2,3-dihydrobiochanin A and oxidised NADP⁺.
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.
