  • The ability to reverse protein aggregation is vital to cells 1 , 2 . Hsp100 disaggregases such as ClpB and Hsp104 are proposed to catalyse this reaction by translocating polypeptide loops through their central pore 3 , 4 . This model of disaggregation is appealing, as it could explain how polypeptides entangled within aggregates can be extracted and subsequently refolded with the assistance of Hsp70 4 , 5 . However, the model is also controversial, as the necessary motor activity has not been… CONTINUE READING
