CC -!- FUNCTION: tRNA cytosine C(5)-methyltransferase that methylates cytosine
CC to 5-methylcytosine (m5C) in tRNAs at position 34 and 48
CC (PubMed:30646830). Trm4a and trm4b methylate different sets of tRNAs
CC (PubMed:30646830). Also methylates cytosine to m5C at positions (60, 61
CC and 62) in tRNA(Asp) (PubMed:23074192). {ECO:0000269|PubMed:23074192,
