Name | tRNA (guanine-N(7)-)-methyltransferase |
| Function | tRNA (guanine-N(7)-)-methyltransferase (EC 2.1.1.33) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to tRNA to form tRNA containing N(7)-methylguanine and S-adenosyl-L-homocysteine. |
| Scope(s) |
Bacteria Eukaryota |
| Example(s) | Q6NU94 (TRMB_XENLA); |
