2.1.1.75 |
| Accepted name: |
apigenin 4′-O-methyltransferase |
| Reaction: |
S-adenosyl-L-methionine + apigenin = S-adenosyl-L-homocysteine + acacetin |
| Glossary: |
apigenin = 4′,5,7-trihydroxyflavone
acacetin = 4′-methoxy-5,7-dihydroxyflavone
naringenin = 4′,5,7-trihydroxyflavan-4-one |
| Other name(s): |
flavonoid O-methyltransferase; flavonoid methyltransferase; S-adenosyl-L-methionine:5,7,4′-trihydroxyflavone 4′-O-methyltransferase |
| Systematic name: |
S-adenosyl-L-methionine:apigenin 4′-O-methyltransferase |
| Comments: |
Converts apigenin into acacetin. Naringenin can also act as an acceptor, but more slowly. |
