Comments [?]

Function Specifically methylates the guanine in position 2445 (m2G2445) and the guanine in position 2069 (m7G2069) of 23S rRNA.
Catalytic activity RHEA:42740: guanosine(2445) in 23S rRNA + S-adenosyl-L-methionine = H(+) + N(2)-methylguanosine(2445) in 23S rRNA + S-adenosyl-L-homocysteine
EC 2.1.1.173
RHEA:43772: guanosine(2069) in 23S rRNA + S-adenosyl-L-methionine = H(+) + N(2)-methylguanosine(2069) in 23S rRNA + S-adenosyl-L-homocysteine
EC 2.1.1.264
Subcellular location Cytoplasm.
Similarity Belongs to the methyltransferase superfamily. RlmKL family.
