DE   Apigenin 4'-O-methyltransferase.
AN   Flavonoid O-methyltransferase.
CA   S-adenosyl-L-methionine + 5,7,4'-trihydroxyflavone = S-adenosyl-L-
CA   homocysteine + 4'-methoxy-5,7-dihydroxyflavone.
CC   -!- Converts apigenin into acacetin.
CC   -!- Naringenin (5,7,4'-trihydroxyflavonone) can also act as acceptor,
CC       more slowly.
