CC   -!- FUNCTION: Catalyzes the 2'-O-methylation of the ribose of cytidine 1402
CC       (C1402) in 16S rRNA. {ECO:0000255|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;
