23S rRNA (guanine2445-N2)-methyltransferase (EC 2.1.1.173, ycbY (gene), rlmL (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (guanine2445-N2)-methyltransferase.[1] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + guanine2445 in 23S rRNA S-adenosyl-L-homocysteine + N2-methylguanine2445 in 23S rRNA

The enzyme methylates 23S rRNA in vitro.
