Flavanone 4-reductase

From Wikipedia, the free encyclopedia

In enzymology, a flavanone 4-reductase (EC 1.1.1.234) is an enzyme that catalyzes the chemical reaction

(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.
