KEGG   ENZYME: 1.14.14.90
Entry
EC 1.14.14.90               Enzyme                                 
Name
isoflavone 2'-hydroxylase;
isoflavone 2'-monooxygenase;
CYP81E1;
CYP Ge-3
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
isoflavone,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (2'-hydroxylating)
Reaction(IUBMB)
an isoflavone + [reduced NADPH---hemoprotein reductase] + O2 = a 2'-hydroxyisoflavone + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R07371]
Reaction(KEGG)
R07371 > R06560 R06561 R06606 R06607 R07746
Substrate
isoflavone [CPD:C00799];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]
Product
2'-hydroxyisoflavone [CPD:C02921];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]
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.
History
EC 1.14.14.90 created 2005 as EC 1.14.13.89, transferred 2018 to EC 1.14.14.90
