CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that
CC specifically methylates the C5 position of cytosine 72 in several
CC tRNAs. {ECO:0000256|HAMAP-Rule:MF_02237}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=cytidine(72) in tRNA + S-adenosyl-L-methionine = 5-
CC methylcytidine(72) in tRNA + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:61988, Rhea:RHEA-COMP:15996, Rhea:RHEA-COMP:15997,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74483, ChEBI:CHEBI:82748; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02237};
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. RsmB/NOP family. {ECO:0000256|HAMAP-Rule:MF_02237}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02237}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
