Name | tRNA guanosine-2'-O-methyltransferase |
| Function | tRNA guanosine-2'-O-methyltransferase (EC 2.1.1.34) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to tRNA to form tRNA containing 2'-O-methylguanosine and S-adenosyl-L-homocysteine. |
| Scope(s) |
Eukaryota Saccharomyces |
| Example(s) | Q07527 (TRM3_YEAST); |
