abstract：:The ATPase activity of DnaK, the 70-kDa chaperone of Escherichia coli, is stimulated by an unfolded protein. However, the stimulation of the DnaK ATPase by unfolded bovine pancreatic trypsin inhibitor can only be observed at low DnaK protein concentrations. At higher DnaK concentrations, the ATPase activity of DnaK ca...
