CC -!- FUNCTION: Specifically methylates the guanine in position 1835
CC (m2G1835) of 23S rRNA. {ECO:0000256|HAMAP-Rule:MF_01859}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(1835) in 23S rRNA + S-adenosyl-L-methionine = H(+) +
CC N(2)-methylguanosine(1835) in 23S rRNA + S-adenosyl-L-homocysteine;

CC Evidence={ECO:0000256|HAMAP-Rule:MF_01859};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01859}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. RlmG family.
CC {ECO:0000256|HAMAP-Rule:MF_01859}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
