The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterized, small proteins that may be involved in translation regulation [1]. The S4 domain probably mediates binding to RNA.
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, Pfam:PF01386. Full length (N- and C-terminal domain) homologues of TL5 are also known as CTC pr ...
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, Pfam:PF01386. Full length (N- and C-terminal domain) homologues 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 Pfam:PF01386). The function of the C-terminal domain of TLC is at present unknown.
Ribosomal protein L25 is an RNA binding protein, that binds 5S rRNA. This family includes Ctc from B. subtilis Swiss:P14194, which is induced by stress.
This family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.
