Apigenin 4'-O-metiltransferaza (EC 2.1.1.75, flavonoidna O-metiltransferaza, flavonoidna metiltransferaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:5,7,4'-trihidroksiflavon 4'-O-metiltransferaza.[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + 4',5,7-trihidroksiflavon S-adenozil-L-homocistein + 4'-metoksi-5,7-dihidroksiflavon
Ovaj enzim konvertuje [[apigenin] u acacetin. Naringenin može takođe da deluje kao akceptor, mada sporo.
