ribosomal protein bL25, Ctc-form; This model models a family of proteins with full-length homology to the general stress protein Ctc of Bacillus subtilis, a mesophile, and ribosomal protein TL5 of Thermus thermophilus, a thermophile. Ribosomal protein L25 of Escherichia coli and H. influenzae appear to be orthologous but consist only of the N-terminal half of Ctc and TL5. Both short (L25-like) and full-length (CTC-like) members of this family bind the E-loop of bacterial 5S rRNA. This protein appears to be restricted to bacteria and organelles, and consists of at most one copy per prokaryotic genome.Ctc of Bacillus subtilis has now been localized to ribosomes and can be viewed as the long form, or Ctc form, of L25. The C-terminal domain of sll1824, an apparent L25 of Synechocystis PCC6803, matches the N-terminal domain of this family. Examples of L25 and Ctc are not separated by a UPGMA tree built on the region of shared homology. [Protein synthesis, Ribosomal proteins: synthesis and modification]

Ribosomal L25/TL5/CTC N-terminal 5S rRNA binding domain; L25 is a single-domain protein, ...
 2-89 2.30e-20

Ribosomal L25/TL5/CTC N-terminal 5S rRNA binding domain; L25 is a single-domain protein, homologous to the N-terminal domain of TL5 and CTC. CTC is a known stress protein, and proteins of this family are believed to have two functions, acting as both ribosomal and stress proteins. In Escherichia coli, cells deleted for L25 were found to be viable; however, these cells grew slowly and had impaired protein synthesis capability. In Bacillus subtilis, CTC is induced under stress conditions and located in the ribosome; it has been proposed that CTC may be necessary for accurate translation under stress conditions. Ribosomal_L25_TL5_CTC is mostly found in bacteria, with a few exceptions such as plants or stramenopiles. Due to its limited taxonomic diversity and the viability of cells deleted for L25, this protein is not believed to be necessary for ribosomal assembly. Eukaryotes contain a protein called L25, which is not homologous to bacterial L25, but rather to bacterial L23.

Ribosomal L25/TL5/CTC N-terminal 5S rRNA binding domain; L25 is a single-domain protein, homologous to the N-terminal domain of TL5 and CTC. CTC is a known stress protein, and proteins of this family are believed to have two functions, acting as both ribosomal and stress proteins. In Escherichia coli, cells deleted for L25 were found to be viable; however, these cells grew slowly and had impaired protein synthesis capability. In Bacillus subtilis, CTC is induced under stress conditions and located in the ribosome; it has been proposed that CTC may be necessary for accurate translation under stress conditions. Ribosomal_L25_TL5_CTC is mostly found in bacteria, with a few exceptions such as plants or stramenopiles. Due to its limited taxonomic diversity and the viability of cells deleted for L25, this protein is not believed to be necessary for ribosomal assembly. Eukaryotes contain a protein called L25, which is not homologous to bacterial L25, but rather to bacterial L23.

 95-178 9.65e-20

Ribosomal protein TL5, C-terminal domain; This family contains the C-terminal domain of ribosomal protein TL5. The N-terminal domain, which binds to 5S rRNA, is contained in family Ribosomal_L25p, pfam01386. Full length (N- and C-terminal domain) homologs of TL5 are also known as CTC proteins. TL5 or CTC are not found in Eukarya or Archaea. In some Bacteria, including E. coli, this ribosomal subunit occurs as a single domain protein (named Ribosomal subunit L25), where the only domain is homologous to TL5 N-terminal domain (hence included in family pfam01386). The function of the C-terminal domain of TLC is at present unknown.
