show Brenda entryEC number
1.14.13.86
Accepted name
2-hydroxyisoflavanone synthase
Reaction
apigenin + 2 NADPH + 2 H+ + O2 = 2-hydroxy-2,3-dihydrogenistein + 2 NADP+ + H2O
Systematic name
apigenin,NADPH:oxygen oxidoreductase (isoflavanone-forming)
CAS registry number
168680-18-0
Comment
A heme-thiolate protein (P-450). EC 4.2.1.105, 2-hydroxyisoflavanone dehydratase, acts on 2-hydroxy-2,3-dihydrogenistein with loss of water and formation of genistein. This may occur spontaneously.
