2.1.1.166

Accepted name:

23S rRNA (uridine²⁵⁵²-2′-O)-methyltransferase

Reaction:

S-adenosyl-L-methionine + uridine²⁵⁵² in 23S rRNA = S-adenosyl-L-homocysteine + 2′-O-methyluridine²⁵⁵² in 23S rRNA

Other name(s):

Um(2552) 23S ribosomal RNA methyltransferase; heat shock protein RrmJ; RrmJ; FTSJ; Um2552 methyltransferase

Systematic name:

S-adenosyl-L-methionine:23S rRNA (uridine²⁵⁵²-2′-O-)-methyltransferase

Comments:

The enzyme catalyses the 2′-O-methylation of the universally conserved U²⁵⁵² in the A loop of 23S rRNA [3].
