Ribosomal protein L31e 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 L31 [1].
  • Plants L31.
  • Yeast L34.
  • Archaeal L31 [2].

These proteins have 87 to 128 amino-acid residues. As a signature pattern, we selected a conserved region located in the central section.
