- (2S)-flavan-4-ol + NADP+ (2S)-flavanone + NADPH + H+
Thus, the two substrates of this enzyme are (2S)-flavan-4-ol and NADP+, whereas its 3 products are (2S)-flavanone, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (2S)-flavan-4-ol:NADP+ 4-oxidoreductase. This enzyme participates in flavonoid biosynthesis.
