Conformational flexibility of the dengue virus RNA dependent RNA polymerase revealed by a complex with an inhibitor

Noble, Christian Guy and Lim, Siew Pheng and Chen, Yen Liang and Shi, Pei-Yong (2013) Conformational flexibility of the dengue virus RNA dependent RNA polymerase revealed by a complex with an inhibitor. Journal of Virology, 87 (9). pp. 5291-5295. ISSN 0022-538X

Abstract

We report a highly reproducible method to crystallize the RNA-dependent RNA polymerase (RdRp) domain of dengue virus serotype 3 (DENV-3), allowing structure refinement to a 1.79-Å resolution and revealing amino acids not seen previously. We also present a DENV-3 polymerase/inhibitor cocrystal structure at a 2.1-Å resolution. The inhibitor binds to the RdRp as a dimer and causes conformational changes in the protein. The improved crystallization conditions and new structural information should accelerate structure-based drug discovery.
