6CYG, 6CYH, 6CYI, 6D1X - PubMed Abstract: 
The hsp90 chaperones govern the function of essential client proteins critical for normal cell function as well as cancer initiation and progression. Hsp90 activity is driven by ATP, which binds to the N-terminal domain and induces large conformational changes that are required for client maturation ...
