TRNA (cytosine38-C5)-methyltransferase

Class of enzymes

TRNA (cytosine38-C5)-methyltransferase (EC 2.1.1.204, hDNMT2 (gene), DNMT2 (gene), TRDMT1 (gene)) is an enzyme with the systematic name S-adenosyl-L-methionine:tRNA (cytosine38-C5)-methyltransferase.[1][2][3] This enzyme catalyses the following chemical reaction:

S-adenosyl-L-methionine + cytosine38 in tRNA S-adenosyl-L-homocysteine + 5-methylcytosine38 in tRNA
Quick Facts Identifiers, EC no. ...

The eukaryotic enzyme catalyses methylation of cytosine38 in the anti-codon loop of tRNAAsp(GTC), tRNAVal(AAC) and tRNAGly(GCC).
