Crystallographic studies, presently on ribosomal and DNA-binding proteins from the moderate thermophile Bacillus stearothermophilus, can be expected to benefit from the use of even more stable proteins from extreme thermophiles. Bacillus caldolyticus, which is able to grow in the temperature range of 70-80 degrees C, appears to be a suitable candidate. We have compared the two bacilli using two criteria: the two-dimensional gel patterns of ribosomal proteins and the properties of DNA-binding protein II. The latter protein is ubiquitous in the eubacterial kingdom and can be purified in large quantities. B. caldolyticus can be grown at 75 degrees C in continuous culture with a generation time of 45-60 min. The yield of ribosomes compares favorably with that of B. stearothermophilus. The gel patterns of the ribosomal proteins are very similar but several differences, in particular among the 50S proteins, are observed. The N-terminal amino-acid sequence of the DNA-binding protein differs in 3 positions (out of 39) from B. stearothermophilus and the protein shows an increased resistance to thermal denaturation. Tetragonal and monoclinic crystals of DNA-binding protein II have been obtained which are suitable for X-ray studies and the diffraction patterns of the two crystal forms are shown.
