CC   -!- FUNCTION: Specifically methylates the cytosine at position 967
CC       (m5C967) of 16S rRNA (By similarity).
CC   -!- CATALYTIC ACTIVITY: S-adenosyl-L-methionine + cytosine(967) in 16S
CC       rRNA = S-adenosyl-L-homocysteine + 5-methylcytosine(967) in 16S
CC       rRNA.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding
CC       methyltransferase superfamily. RsmB/NOP family.
