DNK-metiltransferaza (adenin-specifična) (EC 2.1.1.72, modifikaciona metilaza, restrikcioni modifikacioni sistem) je enzim.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju

S-adenozil-L-metionin + DNK adenin {\displaystyle \rightleftharpoons } S-adenozil-L-homocistein + DNK 6-metilaminopurin

Ovo je velika grupa enzima, većina kojih je ima sličnu specifičnost sa enzimima grupa EC 3.1.21.3, EC 3.1.21.4, i EC 3.1.21.5.
