The hydration state of deep, well-accessible hydrophobic pocket of the metalloprotease thermolysin has been investigated using high-resolution crystallography and isothermal titration calorimetry to understand solvent effects in protein−ligand interactions, a key topic in drug design. The enzyme accessibility could be proved by accommodating noble gas atoms into the pocket in the crystalline state. The noble gases xenon and krypton are known to preferentially bind to desolvated, hydrophobic protein cavities through weak van der Waals interactions. These atoms can, therefore, be used as experimental probes to detect such cavities. |
