IntEnz Enzyme Nomenclature
EC 2.1.1.231

Names

Accepted name:
flavonoid 4'-O-methyltransferase
Other names:
SOMT-2
4'-hydroxyisoflavone methyltransferase
isoflavone methyltransferase
isoflavone O-methyltransferase
Systematic name:
S-adenosyl-L-methionine:flavonoid 4'-O-methyltransferase

Reaction

Comments:

The enzyme catalyses the 4'-methylation of naringenin. In vitro it catalyses the 4'-methylation of apigenin, quercetin, daidzein and genistein.
