抜粋

The amino acid sequences of ribosomal proteins S5 and L30 from Bacillus stearothermophilus have been determined. These proteins have recently been crystallized in our institute. Sequence data were obtained by manual sequencing of peptides derived from cyanogen bromide cleavage and digestion with trypsin and chymotrypsin or thermolysin. Proteins S5 and L30 contain 166 and 62 amino acid residues and have calculated M(r) values of 17,628 and 7,053, respectively. Comparison of the sequences with those of the homologous proteins from Escherichia coli shows 55% identical residues for S5 and 53% for L30. For both proteins, the distribution of conserved and substituted regions is not uniform thoughout the molecule. Secondary structure predictions were carried out for the B. stearothermophilus proteins. Comparison with the results for the homologous E. coli proteins indicated similar secondary structural order for the molecules from the two species.
