FUNCTION: Specifically methylates the N7 position of guanosine in position 527 of 16S rRNA (By similarity).

CATALYTIC ACTIVITY: S-adenosyl-L-methionine + guanosine(527) in 16S rRNA = S-adenosyl-L-homocysteine + N(7)-methylguanosine(527) in 16S rRNA.

FUNCTION: Specifically methylates the N7 position of guanosine in position 535 of 16S rRNA (By similarity).

FUNCTION: Specifically methylates the N7 position of guanosine in position 518 of 16S rRNA (By similarity).

FUNCTION: Specifically methylates the N7 position of a guanosine in 16S rRNA (By similarity).

SUBCELLULAR LOCATION: Cytoplasm (Potential).

SIMILARITY: Belongs to the methyltransferase superfamily. RNA methyltransferase RsmG family.
