Retraction: renaturation of denatured lambda repressor requires heat shock proteins.Cell. 1992 Sep 4;70(5):714. doi: 10.1016/0092-8674(92)90305-v. Cell. 1992. PMID: 1516129 No abstract available.
Abstract
The temperature-sensitive bacteriophage lambda cI857 repressor protein rapidly renatures after thermal inactivation. E. coli mutants in the heat shock protein genes dnaK, dnaJ, and grpE do not efficiently reactivate heat-denatured repressor. Our results suggest that protein refolding is promoted by heat shock proteins and that such a process is the basis of the homeostatic role played by these proteins in the heat shock response.
