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.
