23S rRNA (guanosine2251-2'-O)-methyltransferase (EC 2.1.1.185, rlmB (gene), yifH (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (guanosine2251-2'-O-)-methyltransferase.[1][2] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + guanosine2251 in 23S rRNA S-adenosyl-L-homocysteine + 2'-O-methylguanosine2251 in 23S rRNA
The enzyme catalyses the methylation of guanosine2251.
