title: 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.
abstract: 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.
