show Brenda entryEC number
1.1.1.348
Accepted name
(3R)-2′-hydroxyisoflavanone reductase
Reaction
a (4R)-4,2′-dihydroxyisoflavan + NADP+ = a (3R)-2′-hydroxyisoflavanone + NADPH + H+
Other name(s)
vestitone reductase,
pterocarpin synthase (incorrect),
pterocarpan synthase (incorrect)
Systematic name
(3R)-2′-hydroxyisoflavanone:NADP+ 4-oxidoreductase
CAS registry number
118477-70-6
Comment
This plant enzyme participates in the biosynthesis of the pterocarpan phytoalexins medicarpin, maackiain, and several forms of glyceollin. The enzyme has a strict stereo specificity for the 3R-isoflavanones.
