| Glossary: |
naringenin = 4′,5,7-trihydroxyflavan-4-one |
| Other name(s): |
SOMT-2; 4′-hydroxyisoflavone methyltransferase |
| Systematic name: |
S-adenosyl-L-methionine:flavonoid 4′-O-methyltransferase |
| Comments: |
The enzyme catalyses the 4′-methylation of naringenin. In vitro it catalyses the 4′-methylation of apigenin, quercetin, daidzein and genistein. |
