CC -!- FUNCTION: Specifically methylates the cytosine at position 967 (m5C967)
CC of 16S rRNA. {ECO:0000256|ARBA:ARBA00002724}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=cytidine(967) in 16S rRNA + S-adenosyl-L-methionine = 5-
CC methylcytidine(967) in 16S rRNA + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:42748, Rhea:RHEA-COMP:10219, Rhea:RHEA-COMP:10220,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74483, ChEBI:CHEBI:82748; EC=2.1.1.176;
CC Evidence={ECO:0000256|ARBA:ARBA00000588};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. RsmB/NOP family. {ECO:0000256|PROSITE-ProRule:PRU01023}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU01023}.
