Summary: Ribosomal RNA large subunit methyltransferase D, RlmJ
Ribosomal RNA large subunit methyltransferase D, RlmJ Provide feedback
RlmJ is ribosomal RNA large subunit methyltransferase J is required for full methylation of 23S ribosomal RNA (rRNA) during ribosome biogenesis. The ribosomal RNA of E. coli carries 24 residues that require methylation, and this methyltransferase is the last to be described, that modifies A2030 . RlmJ displays a variant of the Rossmann-like methyltransferase (MTase) fold with an inserted helical subdomain. On binding cofactor and substrate a large shift of the N-terminal motif X tail is induced in order to make it cover the cofactor-binding site and to trigger active-site changes in motifs IV and VIII .

InterPro entry IPR007473Ribosomal methyltransferase RlmJ (YhiR) specifically methylates the adenine in position 2030 of 23S rRNA [PUBMED:22847818, PUBMED:23945937]. Nascent 23S rRNA seems to be the natural substrate. RlmJ seems to be required for the utilisation of extracellular DNA as the sole source of carbon and energy [PUBMED:16707682].

A class of redox enzymes are two domain proteins. One domain, termed the catalytic domain, confers substrate specificity and the precise reaction of the enzyme. The other domain, which is common to this class of redox enzymes, is a Rossmann-fold domain. The Rossmann domain binds nicotinamide adenine dinucleotide (NAD+) and it is this cofactor that reversibly accepts a hydride ion, which is lost or gained by the substrate in the redox reaction. Rossmann domains have an alpha/beta fold, which has a central beta sheet, with approximately five alpha helices found surrounding the beta sheet.The strands forming the beta sheet are found in the following characteristic order 654123. The inter sheet crossover of the stands in the sheet form the NAD+ binding site . In some more distantly relate Rossmann domains the NAD+ cofactor is replaced by the functionally similar cofactor FAD.

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the RsmJ domain has been found. There are 9 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
