Danilo, The protein cavity can be analyzed utilizing the program Voidoo ( Kleywegt GJ, 1994). This program uses an atomic-flattening algorithm based on a 3-dimensional grid to locate and delineate different cavities. A Van Der Waals cavity can further be generated with a probe radius with a computed cavity grid using the highest number of grid points, and a contact and accessible surface can further be evaluated...
