Abstract: Escherichia coli ClpB is a molecular chaperone that belongs to the Clp/Hsp100 family of AAA+ proteins. ClpB is able to form a hexameric ring structure to catalyze protein disaggregation with the assistance of the DnaK chaperone system. Our knowledge of the mechanism of how ClpB recognizes its substrates is still limited. In this study, we have quantitatively investigated ClpB binding to a number of unstructured polypeptides using steady-state anisotropy titrations. To precisely determine the binding affinity f…
