title: Molecular chaperones: structure of a protein disaggregase.
abstract: The ring-forming molecular chaperone Hsp104/ClpB is a member of the AAA+ protein family which rescues proteins from aggregated states. The newly determined crystal structure of ClpB provides new insights into the mechanism of protein disaggregation, suggesting a crowbar activity mediated by a unique coiled-coil domain.
