23S rRNA (uridine2552-2'-O)-methyltransferase (EC 2.1.1.166, Um(2552) 23S ribosomal RNA methyltransferase, heat shock protein RrmJ, RrmJ, FTSJ, Um2552 methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (uridine2552-2'-O-)-methyltransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + uridine2552 in 23S rRNA [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + 2'-O-methyluridine2552 in 23S rRNA
The enzyme catalyses the 2'-O-methylation of the universally conserved U2552 in the A loop of 23S rRNA.
