Protein

Ribosomal RNA large subunit methyltransferase M

Gene

rlmM

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the 2'-O-methylation at nucleotide C2498 in 23S rRNA. Modifies C2498 in naked 23S rRNA, but not in assembled 50S subunits or ribosomes.2 Publications

Catalytic activityi

S-adenosyl-L-methionine + cytidine(2498) in 23S rRNA = S-adenosyl-L-homocysteine + 2'-O-methylcytidine(2498) in 23S rRNA.2 Publications
