AB  - Multiple Solvent Crystal Structures (MSCS) is a crystallographic technique to
      identify energetically favorable positions and orientations of small organic
      molecules on the surface of proteins. We determined the high-resolution crystal
      structures of thermolysin (TLN), generated from crystals soaked in 50--70%
      acetone, 50--80% acetonitrile and 50 mM phenol. The structures of the protein in 
      the aqueous-organic mixtures are essentially the same as the native enzyme and a 
      number of solvent interaction sites were identified. The distribution of probe
      molecules shows clusters in the main specificity pocket of the active site and a 
      buried subsite. Within the active site, we compared the experimentally determined
      solvent positions with predictions from two computational functional group
      mapping techniques, GRID and Multiple Copy Simultaneous Search (MCSS). The
      experimentally determined small molecule positions are consistent with the
      structures of known protein--ligand complexes of TLN.
