CC   -!- FUNCTION: Specifically methylates the guanine in position 1835
CC       (m2G1835) of 23S rRNA. {ECO:0000255|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;
