MRM3

Functionⁱ

S-adenosyl-L-methionine-dependent 2'-O-ribose methyltransferase that catalyzes the formation of 2'-O-methylguanosine at position 1370 (Gm1370) in the 16S mitochondrial large subunit ribosomal RNA (mtLSU rRNA), a conserved modification in the peptidyl transferase domain of the mtLSU rRNA.3 Publications

Catalytic activityⁱ

S-adenosyl-L-methionine + guanosine(1370) in 16S rRNA = S-adenosyl-L-homocysteine + 2'-O-methylguanosine(1370) in 16S rRNA.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:

100%	UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%	UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%	UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
