ABSTRACT
The replication of flaviviruses requires the correct processing of their polyprotein by the viral NS3 protease (NS3pro). Essential for the activation of NS3pro is a 47-residue region of NS2B. Here we report the crystal structures of a dengue NS2B-NS3pro complex and a West Nile virus NS2B-NS3pro complex with a substrate-based inhibitor. These structures identify key residues for NS3pro substrate recognition and clarify the mechanism of NS3pro activation.
