-The E. coli Hsp70, DnaK, is a crucial protein chaperone whose function is to reduce bind exposed hydrohpobic residues of unfolded proteins, which prevents aggregation and rescues the nascent chain from kinetic traps along the folding pathway. Hsp70 protein chaperones switch between an <scene name='60/609794/Atp-dnak/1'>ATP-bound</scene>, low-substrate affinity form and an <scene name='60/609794/Adp-dnak_1/4'>ADP-bound</scene>, high substrate affinity form during their allosteric cycle.[http://www.ncbi.nlm.nih.gov/pubmed/23123194?dopt=Abstract] [http://www.ncbi.nlm.nih.gov/pubmed/19439666?dopt=Abstract] Hsp70 protein chaperones are ubiquitously found in almost all known organisms and cell types and represent a potential target for anti-cancer and neurodegenerative therapies.[http://www.ncbi.nlm.nih.gov/pubmed/21403392]
