摘要
The Hsp90 chaperone is responsible for the stabilization of a large variety of regulatory proteins. Single-molecule FRET was used to examine the conformational dynamics of Hsp90 in its different nucleotide-bound states. The findings suggest that, in the absence of substrate and cochaperone proteins, Hsp90's conformational changes are not strongly coupled to ATP hydrolysis.
