IntEnz Enzyme Nomenclature
EC 2.1.1.75

Names

Accepted name:
apigenin 4'-O-methyltransferase
Other names:
flavonoid O-methyltransferase
flavonoid methyltransferase
Systematic name:
S-adenosyl-L-methionine:apigenin 4'-O-methyltransferase

Reaction

Comments:

Converts apigenin into acacetin. Naringenin (5,7,4'-trihydroxyflavanone) can also act as an acceptor, but more slowly.
