TRNK (adenin9-N1)-metiltransferaza (EC 2.1.1.218, Trm10p, tRNK(m1G9/m1A9)-metiltransferaza, tRNK(m1G9/m1A9)MTaza, TK0422p (gen), tRNK m1A9-metiltransferaza, tRNK m1A9 MTaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:tRNK (adenin9-N1)-metiltransferaza.[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + adenin9 u tRNK S-adenozil-L-homocistein + N1-metiladenin9 u tRNK
Enzim iz Sulfolobus kiselinaocaldarius specifično metiluje adenin9 u tRNK. Bifunkcionalani enzim iz Thermococcus kodakaraensis takođe katalizuje metilaciju guanina9 u tRNK (cf. EC 2.1.1.221, tRNK (guanin9-N1)-metiltransferaza).
