Polar Desolvation and Position 226 of Pancreatic and Neutrophil Elastases Are Crucial to their Affinity for the Kunitz-Type Inhibitors ShPI-1 and ShPI-1/K13L.
The Kunitz-type protease inhibitor ShPI-1 inhibits human neutrophil elastase (HNE, Ki = 2.35·10-8 M) but does not interact with the porcine pancreatic elastase (PPE); whereas its P1 site variant, ShPI-1/K13L, inhibits both HNE and PPE (Ki = 1.3·10-9 M, and Ki = 1.2·10-8 M, respectively). By employin...
