Protein name
RecName: Full=tRNA (cytosine(72)-C(5))-methyltransferase;
Short=tRNA:m(5)C72 MTase;
EC 2.1.1.-;

Comments [?]

Function S-adenosyl-L-methionine-dependent methyltransferase that specifically methylates the C5 position of cytosine 72 in several tRNAs.
Catalytic activity RHEA:61988: cytidine(72) in tRNA + S-adenosyl-L-methionine = 5-methylcytidine(72) in tRNA + H(+) + S-adenosyl-L-homocysteine
PhysiologicalDirection=left-to-right (RHEA:61989)
Similarity Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
