Ribosomal protein S8 signature


Ribosomal protein S8 is one of the proteins from the small ribosomal subunit. In Escherichia coli, S8 is known to bind directly to 16S ribosomal RNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1], groups:

  • Eubacterial S8.
  • Algal and plant chloroplast S8.
  • Cyanelle S8.
  • Archaebacterial S8.
  • Marchantia polymorpha mitochondrial S8.
  • Mammalian S15A.
  • Plant S15A.
  • Yeast S22 (S24).

As a signature pattern, we selected the best conserved region located in the C-terminal section of these proteins.
