CC -!- FUNCTION: Mitochondrial tRNA methyltransferase that mediates
CC methylation of cytosine to 5-methylcytosine (m5C) at position 34 of mt-
CC tRNA(Met). mt-tRNA(Met) methylation at cytosine(34) takes place at the
CC wobble position of the anticodon and initiates the formation of 5-
CC formylcytosine (f(5)c) at this position. mt-tRNA(Met) containing the
CC f(5)c modification at the wobble position enables recognition of the
CC AUA codon in addition to the AUG codon, expanding codon recognition in
CC mitochondrial translation. {ECO:0000250|UniProtKB:Q9H649}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=cytidine(34) in mitochondrial tRNA + S-adenosyl-L-methionine =
CC 5-methylcytidine(34) in mitochondrial tRNA + H(+) + S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:53076, Rhea:RHEA-COMP:13451, Rhea:RHEA-
