CC   -!- FUNCTION: Specifically methylates the N4 position of cytidine in
CC       position 1402 (C1402) of 16S rRNA. {ECO:0000255|HAMAP-Rule:MF_01007}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=cytidine(1402) in 16S rRNA + S-adenosyl-L-methionine = H(+) +
CC         N(4)-methylcytidine(1402) in 16S rRNA + S-adenosyl-L-homocysteine;
