Abstract
Hsp100 family of molecular chaperones shows a unique capability to resolubilize and reactivate aggregated proteins. The Hsp100-mediated protein disaggregation is linked to the activity of other chaperones from the Hsp70 and Hsp40 families. The best-studied members of the Hsp100 family are the bacterial ClpB and Hsp104 from yeast. Hsp100 chaperones are members of a large super-family of energy-driven conformational "machines" known as AAA+ ATPases. This review describes the current mechanistic model of the chaperone-induced protein disaggregation and explains how the structural architecture of Hsp100 supports disaggregation and how the co-chaperones may participate in the Hsp100-mediated reactions.
