Function
This antibody catalyzes the 3-beta-hydroxylation of 2S-flavanones to 2R,3R-dihydroflavonols. These dihydroflavonols are key intermediates in the biosynthesis of flavonols, anthocyanidins, catechins, and proanthocyanidins in plants. In vitro, this antibody converts (2S)-eriodictyol to (+)-taxifolin and (2S)-naringenin to (+)-(2R/3R)-dihydrokaempferol.
