West Nile Virus NS2B/NS3protease in complex with Bz-Nle-Lys-Arg-Arg-H

Overview

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.

About this Structure

2FP7 is a Protein complex structure of sequences from West nile virus with NDL as ligand. Active as Flavivirin, with EC number 3.4.21.91 Full crystallographic information is available from OCA.
