The allosteric mechanism of Hsp70 molecular chaperones enables ATP binding to the N-terminal nucleotide-binding domain (NBD) to alter substrate affinity to the C-terminal substrate-binding domain (SBD) and substrate binding to enhance ATP hydrolysis. Cycling between ATP-bound and ADP/substrate-bound states requires Hsp70s to visit a state with high ATPase(More)
Protein folding in cells is regulated by networks of chaperones, including the heat shock protein 70 (Hsp70) system, which consists of the Hsp40 cochaperone and a nucleotide exchange factor. Hsp40 mediates complex formation between Hsp70 and client proteins prior to interaction with Hsp90. We used mass spectrometry (MS) to monitor assemblies formed between(More)
