23S rRNA (guanine2445-N2)-methyltransferase

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. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + guanine2445 in 23S rRNA ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + N2-methylguanine2445 in 23S rRNA The enzyme methylates 23S rRNA in vitro.
