Human furin Cys198 imposes dihedral and positional restraints on His194 for optimal Ser386-proton transfer.

Abstract excerpt

Inhibitors of human furin may represent the clinical remedy for very aggressive cancer, viral, and bacterial infections. Most of the currently available inhibitors are weak in terms of potency, drug-likeness, and furin specificity thereby necessitating the development of newer compounds especially mechanism-based inhibitors. Here, the roles of active site Cys198 (C198), His194 (H194), and Ser386 (S386) were...
