Figure 1

Comparison of crystal structures (cartoon representation) of yeast Hsp90 with bound AMPNPP (A, pdb2cg9), a Hsp90-Cdc37-Cdk4 complex bound with ATP (B, pdb5fwl), a mitochondrial homolog with bound ADP (C, pdb2o1v), a bacterial homolog with bound ADP (D, pdb2ioq) and an “open” ADP-bound structure based on sFRET data (E, Hellenkamp et al., 2016). In (A) the location of the N-, M-, and C-domains is indicated and color-coded for one monomer, the second monomer is in gray. In case of (B–E) one monomer is colored from light (N) to dark (C), while the other is in gray for visibility. The colors range from blueish (closed conformation) to reddish (open conformation).
