General annotation (Comments)

Function	Specifically methylates the guanine in position 2445 (m2G2445) and the guanine in position 2069 (m7G2069) of 23S rRNA By similarity. HAMAP-Rule MF_01858
Catalytic activity	S-adenosyl-L-methionine + guanine(2445) in 23S rRNA = S-adenosyl-L-homocysteine + N(2)-methylguanine(2445) in 23S rRNA. HAMAP-Rule MF_01858 S-adenosyl-L-methionine + guanine(2069) in 23S rRNA = S-adenosyl-L-homocysteine + N(7)-methylguanine(2069) in 23S rRNA. HAMAP-Rule MF_01858
Subcellular location	Cytoplasm Potential HAMAP-Rule MF_01858.
Sequence similarities	Belongs to the methyltransferase superfamily. RlmKL family. Contains 1 THUMP domain.
