Abstract:
The major heat shock proteins of Staphylococcus aureus had apparent Mrs of 84,000, 76,000, and 60,000, and other prominent proteins of Mrs 66,000, 51,000, 43,000 and 24,000 were also induced. Staphylococcus epidermidis showed a similar response. These proteins were also induced by CdCl2, ethanol and apparently osmotic stress (1.71 M NaCl or 2.25 M sucrose). Most of the proteins sedimented with the membrane fraction, but the Mr 60,000 protein remained in the cytoplasm.
