|
Sysname |
S-adenosyl-L-methionine:apigenin 4'-O-methyltransferase
|
Reaction(IUBMB) |
S-adenosyl-L-methionine + apigenin = S-adenosyl-L-homocysteine + acacetin [RN: R03571]
|
Reaction(KEGG) |
|
Substrate |
|
Product |
S-adenosyl-L-homocysteine [CPD: C00021];
acacetin [CPD: C01470]
|
Comment |
Converts apigenin into acacetin. Naringenin can also act as an acceptor, but more slowly.
