DE   2'-hydroxydaidzein reductase.
AN   2'-hydroxydihydrodaidzein:NADP(+) 2'-oxidoreductase.
AN   HDR.
AN   NADPH:2'-hydroxydaidzein oxidoreductase.
CA   2'-hydroxy-2,3-dihydrodaidzein + NADP(+) = 2'-hydroxydaidzein + 2 H(+) +
CA   NADPH.
CC   -!- In the reverse reaction, the 2'-hydroxyisoflavone
CC       (2'-hydroxydaidzein) is reduced to an isoflavanone.
CC   -!- Also acts on 2'-hydroxyformononetin and to a small extent on
CC       2'-hydroxygenistein.
CC   -!- Involved in the biosynthesis of the phytoalexin glyceollin.
CC   -!- The isoflavones biochanin A, daidzein and genestein as well as the
CC       flavonoids apigenin, kaempferol and quercetin do not act as
CC       substrates.
