3,7-dimetilkvercetin 4'-O-metiltransferaza (EC 2.1.1.83, flavonolna 4'-O-metiltransferaza, flavonolna 4'-metiltransferaza, 4'-OMT, S-adenozil-L-metionin:3',4',5-trihidroksi-3,7-dimetoksiflavon 4'-O-metiltransferaza, 3,7-dimetilkvercitinska 4'-O-metiltransferaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:5,3',4'-trihidroksi-3,7-dimetoksiflavon 4'-O-metiltransferaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + 5,3',4'-trihidroksi-3,7-dimetoksiflavon S-adenozil-L-homocistein + 5,3'-dihidroksi-3,7,4'-trimetoksiflavon
3,7-Dimetilquercetagetin može takođe da deluje kao akceptor.
