PREDICTION OF NOVEL SERINE PROTEASE INHIBITORS
Overview
We describe here the use of a rapid computational method to predict the, relative binding strengths of a series of small-molecule ligands for the, serine proteinase trypsin. Flexible molecular models of the ligands were, docked to the proteinase using an all-atom potential set, without cutoff, limits for the non-bonded and electrostatic energies. The binding-strength, calculation is done directly in terms of a molecular mechanics potential., The binding of eighteen different compounds, including non-binding, controls, has been successfully predicted. The measured Ki is correlated, with the predicted energy. The correctness of the theoretical calculations, is demonstrated with both kinetics measurements and X-ray structure, determination of six enzyme-inhibitor complexes.
