Functionⁱ

Catalyzes the formation of 2'O-methylated cytidine (Cm32) or 2'O-methylated uridine (Um32) at position 32 in tRNA (PubMed:16848900, PubMed:24951554, PubMed:26202969). Can also methylate adenosine or guanosine, even though these nucleosides are rare or absent at position 32 in the anticodon loop of tRNA (PubMed:24951554).3 Publications
