TRNK (karboksimetiluridin34-5-O)-metiltransferaza (EC 2.1.1.229, ALKBH8, ABH8, Trm9, tRNK metiltransferaza 9) je enzim sa sistematskim imenom S-adenozil-L-metionin:tRNK (karboksimetiluridin34-5-O)-metiltransferaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + karboksimetiluridin34 u tRNK S-adenozil-L-homocistein + 5-(2-metoksi-2-oksoetil)uridin34 u tRNK
Ovaj enzim katalizuje posttranslacionu modifikaciju uridinskih ostataka u pokretnoj poziciji 34 antikodonske petlje tRNK.
