Changes in PDFs of the torsion angles of PTAP (a–d) and Tsg101 (e–h) that lose the most uncorrelated entropy on binding. Dashed lines: free state. Solid lines: bound state. The heavy bonds indicate the central bond of the dihedral. The entropic free energy changes, −T ΔS, (kcal mol−1) are given in the upper-right corner of each frame.
