 Zusammenfassung: Cell survival under severe thermal stress requires the activity of a bi-chaperone system, consisting of the ring-forming AAA+ chaperone ClpB (Hsp104) and the DnaK (Hsp70) chaperone system, which acts to solubilize and reactivate aggregated proteins. Recent studies have provided novel insight into the mechanism of protein disaggregation, demonstrating that ClpB/Hsp104 extracts unfolded polypeptides from an aggregate by threading them through its central pore. This translocation activity is necessary but not sufficient for aggregate solubilization. In addition, the middle (M) domain of ClpB and the DnaK system have essential roles, possibly by providing an unfolding force, which facilitates the extraction of misfolded proteins from aggregates.
