Kafeat O-metiltransferaza (EC 2.1.1.68, kafeatna metiltransferaza, kafeatna 3-O-metiltransferaza, S-adenozil-L-metionin:kafeinska kiselina-O-metiltransferaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:3,4-dihidroksi-trans-cinamat 3-O-metiltransferaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + 3,4-dihidroksi-trans-cinamat S-adenozil-L-homocistein + 3-metoksi-4-hidroksi-trans-cinamat
3,4-Dihidroksibenzaldehid i katehol mogu da deluju kao akceptori, mada je reakcija sporija.
