FIG. 3. Superposition of the ProX binding site in the open and closed conformations. Stereo picture of the superposition of ProX in the open conformation (blue) onto the closed conformation (red). GB (green) is shown as the ligand in the closed form. Residues involved in ligand binding and the ligand are drawn as ball-and-stick model and labeled with their residue names.
