show Brenda entryEC number
1.14.14.90
Accepted name
isoflavone 2′-hydroxylase
Reaction
an isoflavone + [reduced NADPH—hemoprotein reductase] + O2 = a 2′-hydroxyisoflavone + [oxidized NADPH—hemoprotein reductase] + H2O
Other name(s)
isoflavone 2′-monooxygenase,
CYP81E1,
CYP Ge-3
Systematic name
isoflavone,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (2′-hydroxylating)
CAS registry number
110183-49-8
Comment
A cytochrome P-450 (heme-thiolate) protein. Acts on daidzein, formononetin and genistein. EC 1.14.14.89, 4′-methoxyisoflavone 2′-hydroxylase, has the same reaction but is more specific as it requires a 4′-methoxyisoflavone.
