ABSTRACT: Dengue virus, belongs to Flaviviridae, is an arthropod transmitted virus that threatens millions of people’s lives. As with other flaviviruses, a positive single-stranded 11-kilobases RNA in the dengue virus genome encodes three structural proteins (capsid protein C, membrane protein M, and envelope protein E) and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). The two component protease NS2B–NS3p is essential for viral replication and is believed to be a potential antiviral drug target. Aprotinin, a native inhibitor, is proved to retard the activity of NS2B–NS3p. The backbone assignments of NS2B–NS3p will be essential for determining the high resolution solution structure of NS2B–NS3p and screening new antiviral drugs. Herein, we report the backbone 1H, 15N, 13C resonance assignments of the N terminal fragment of NS2B (4.8 kDa) and NS3p (18.5 kDa) in complex with aprotinin (6.5 kDa) by high resolution NMR.
