MRM3-like substrate binding domain

MRM3 catalyses 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 [1-3]. This entry represents the substrate binding domain of MRM3 from animals and related sequences from bacteria. Paper describing PDB structure 1ipa. [1]. 12077432.
