RL Submitted (NOV-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the 2'-O-methylation of the ribose of cytidine 1402
CC (C1402) in 16S rRNA. {ECO:0000256|HAMAP-Rule:MF_01877}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=cytidine(1402) in 16S rRNA + S-adenosyl-L-methionine = 2'-O-
CC methylcytidine(1402) in 16S rRNA + H(+) + S-adenosyl-L-homocysteine;

CC Evidence={ECO:0000256|HAMAP-Rule:MF_01877};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01877}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. RsmI family.
CC {ECO:0000256|HAMAP-Rule:MF_01877}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
