Protonation states as at pH7, atom- and bond-types, hydrogen addition, and consideration of active site waters for inclusion/exclusion were implemented using SYBYL ® 7.0 for the crystal struct... res (PDB Codes: 1YC1 / 1YC3 / 1YC4 [ 29 ], 1BYQ [ 30 ]) containing the ligands 4BC (Figure 1 ), 43P (Figure 1 ), and ADP bound to the N-terminal ATP binding domain of human Hsp90α.
Results and discussion We analysed crystal structures (PDB Codes: 1YC1 / 1YC3 / 1YC4 [ 29 ], 1BYQ [ 30 ]) containing the ligands 4BC (Figure 1 ), 43P (Figure 1 ), and ADP (Figure 2 ) bound to the N-terminal ATP binding domain of human Hsp90α, as described in detail in the Methods section.

The RMSD was calculated between each docked ligand and its later published crystallographic conformation (PDB Codes: 1YC1 / 1YC3 / 1YC4 ) (Table 1 and Figures 3 , 4).
The RMSD values between the docked ligands and their crystallographic conformations (1YC1/1YC3/1YC4) are given in Table 1 .
