CC -!- FUNCTION: Specifically methylates the guanine in position 966 of 16S
CC rRNA in the assembled 30S particle. {ECO:0000256|ARBA:ARBA00002649,
CC ECO:0000256|PIRNR:PIRNR004553}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(966) in 16S rRNA + S-adenosyl-L-methionine = H(+) +
CC N(2)-methylguanosine(966) in 16S rRNA + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:23548, Rhea:RHEA-COMP:10211, Rhea:RHEA-COMP:10212,

CC Evidence={ECO:0000256|ARBA:ARBA00000252,
CC ECO:0000256|PIRNR:PIRNR004553};
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. RsmD family.
CC {ECO:0000256|ARBA:ARBA00005269, ECO:0000256|PIRNR:PIRNR004553}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
