Ribosomal protein L39e signature


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

  • Mammalian L39 [1].
  • Plants L39.
  • Yeast L46 [2].
  • Archebacterial L39e [3].

These proteins are very basic. About 50 residues long, they are the smallest proteins of eukaryotic-type ribosomes. As a signature pattern, we selected a conserved region in the C-terminal section of these proteins.
