ID 1.14.14.89 DE 4'-methoxyisoflavone 2'-hydroxylase. AN CYP81E1. AN CYP81E3. AN CYP81E7. AN isoflavone 2'-hydroxylase. AN isoflavone 2'-monooxygenase. CA formononetin + O2 + reduced [NADPH--hemoprotein reductase] = CA 2'-hydroxyformononetin + H(+) + H2O + oxidized [NADPH--hemoprotein CA reductase]. CC -!- A cytochrome P450 (heme-thiolate) protein. CC -!- Acts on isoflavones with a 4'-methoxy group, such as formononetin and CC biochanin A. CC -!- Involved in the biosynthesis of the pterocarpin phytoalexins CC medicarpin and maackiain. CC -!- EC 1.14.14.90 is less specific and acts on other isoflavones as well CC as 4'-methoxyisoflavones. CC -!- Formerly EC 1.14.13.53. DR Q6WNR0, C81E7_MEDTR; //
