23S rRNA (guanine1835-N2)-methyltransferase (EC 2.1.1.174 ygjO (gene) rlmG (gene) ribosomal RNA large subunit methyltransferase G) is an enzyme with system name S-adenosyl-L-methionine:23S rRNA (guanine1835-N2)-methyltransferase. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + guanine1835 in 23S rRNA S-adenosyl-L-homocysteine + N2-methylguanine1835 in 23S rRNAThe enzyme methylates 23S rRNA in vitro assembled 50S subunits are not a substrate.
