TRNA (carboxymethyluridine34-5-O)-methyltransferase (EC 2.1.1.229, ALKBH8, ABH8, Trm9, tRNA methyltransferase 9) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (carboxymethyluridine34-5-O)-methyltransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + carboxymethyluridine34 in tRNA [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + 5-(2-methoxy-2-oxoethyl)uridine34 in tRNA
The enzyme catalyses the posttranslational modification of uridine residues at the wobble position 34 of the anticodon loop of tRNA.
