The amino acid sequence of the ribosomal protein S8 of Escherichia coli.
The primary structure of protein S8 from the 30S subunit of Escherichia coli ribosomes has been determined by sequencing the peptides derived from tryptic, chymotryptic, thermolytic and staphylococcal protease digestion of the protein. Protein S8 has 129 amino acid residues which result in a molecular weight of 13996. The N-terminal part of the sequence up to position 68 is in complete agreement with the reported sequence data[1,2]. However, differences exist in the C-terminal half, where an additional hydrophobic tryptic peptide has been found.
