On the DNA binding protein II from Bacillus stearothermophilus. II. The amino acid sequence and its relation to those of homologous proteins from other prokaryotes.
The complete amino acid sequence of DNA binding protein II from Bacillus stearothermophilus has been determined. The protein contains 90 amino acid residues and has a calculated Mr of 9716. The sequence is compared to homologous molecules from Escherichia coli, Thermoplasma acidophilum, and Pseudomonas aeruginosa (where only a partial sequence is available). The B. stearothermophilus molecule has 58% and 59% residues identical with the two forms of the E. coli protein and 32% with the T. acidophilum protein. There are totally conserved residues at positions 46-48 and 61-65 with an intervening cluster of basic amino acids in all four proteins.
