Ribosomal protein S3 signature





Description

Ribosomal protein S3 is one of the proteins from the small ribosomal subunit. In Escherichia coli, S3 is known to be involved in the binding of initiator Met-tRNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1], groups:

  • Eubacterial S3.
  • Algal and plant chloroplast S3.
  • Cyanelle S3.
  • Archaebacterial S3.
  • Plant mitochondrial S3.
  • Vertebrate S3.
  • Insect S3.
  • Caenorhabditis elegans S3 (C23G10.3).
  • Yeast S3 (Rp13).

S3 is a protein of 209 to 559 amino-acid residues. As signature patterns, we selected a conserved region located in the C-terminal section.
