title: Chaperoned protein disaggregation--the ClpB ring uses its central channel.
abstract: In this issue of Cell, exploit a clever manipulation of the Hsp100 ring chaperone, ClpB, to gain some mechanistic and physiologic understanding of the action of this chaperone in mediating ATP-dependent disaggregation of protein aggregates that accumulate in the bacterial cytoplasm under severe heat shock conditions.
