Structural and Functional Analysis of the Middle Segment of Hsp90: Implications for ATP Hydrolysis and Client Protein and Cochaperone Interactions
Open accessAbstract
Activation of client proteins by the Hsp90 molecular chaperone is dependent on binding and hydrolysis of ATP, which drives a molecular clamp via transient dimerization of the N-terminal domains. The crystal structure of the middle segment of yeast Hsp90 reveals considerable evolutionary divergence from the equivalent regions of other GHKL protein family members such as MutL and GyrB, including an additional domain of new fold. Using the known structure of the N-terminal nucleotide binding domain, a model for the Hsp90 dimer has been constructed. From this structure, residues implicated in the ATPase-coupled conformational cycle and in interactions with client proteins and the activating cochaperone Aha1 have been identified, and their roles functionally characterized in vitro and in vivo.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
