Isoflavone 3'-hydroxylase (EC 1.14.14.88, Formerly EC 1.14.13.52) is an enzyme that catalyzes the chemical reaction
Isoflavone 3'-hydroxylase is a cytochrome P450 protein containing heme. It requires a partner cytochrome P450 reductase for functional expression. This uses nicotinamide adenine dinucleotide phosphate (NADPH). The systematic name of this enzyme class is formononetin,NADPH:oxygen oxidoreductase (3'-hydroxylating). It is also called isoflavone 3'-monooxygenase. The enzyme isolated from chickpea is part of the biosynthetic pathway to pterocarpans which act as phytoalexins.
