This model, using real molecular thermodynamics, shows a docking process, in which one particle is "captured" by another. The user can manipulate the charge and participate in what is a central problem in enzyme catalysis and antigen-antibody interactions.
The shapes of molecular surfaces and electrostatic potential distributions are believed to be the major factors that govern docking.
