Ribosomal protein S8e signature


A number of eukaryotic and archaebacterial ribosomal proteins can be grouped on the basis of sequence similarities [1]. One of these families consists of:

  • Mammalian S8.
  • Caenorhabditis elegans S8 (F42C5.8).
  • Leishmania major S8.
  • Plant S8.
  • Yeast S8 (S14) (Rp19).
  • Archebacterial S8e.

These proteins have either about 220 amino acids (in eukaryotes) or about 125 amino acids (in archebacteria). As a signature pattern we selected a conserved stretch which is located in the N-terminal section and which is rich in positively charged residues.
