Enzyme Information
| 2.1.1.204 |
tRNA (cytosine(38)-C(5))-methyltransferase.
based on mapping to UniProt O14717
S-adenosyl-L-methionine + cytosine(38) in tRNA = S-adenosyl-L- homocysteine + 5-methylcytosine(38) in tRNA.
-!- The eukaryotic enzyme catalyzes methylation of cytosine(38) in the anti-codon loop of tRNA(Asp)(GTC), tRNA(Val)(AAC) and tRNA(Gly)(GCC). -!- Methylation by Dnmt2 protects tRNAs against stress-induced cleavage by ribonuclease. -!- Formerly EC 2.1.1.29.
