Template:Infobox enzyme TRNA (cytosine34-C5)-methyltransferase (Template:EC number, hTrm4 Mtase, hTrm4 methyltransferase, hTrm4 (gene), tRNA:m5C-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (cytosine34-C5)-methyltransferase.[1] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + cytosine34 in tRNA precursor S-adenosyl-L-homocysteine + 5-methylcytosine34 in tRNA precursor

The human enzyme is specific for C5-methylation of cytosine34 in tRNA precursors.
