Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.82Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function POLG_BVDVN Initial binding to target cell probably involves interaction of E(rns) with glycosaminoglycans. E1 and/or E2 are responsible of cell attachment with CD46 and subsequent fusion after internalization of the virion by endocytosis (Probable). P7 forms a leader sequence to properly orient NS2 in the membrane (By similarity). Uncleaved NS2-3 is required for production of infectious virus. NS2 protease seems to play a vital role in viral RNA replication control and in the pathogenicity of the virus. NS3 displays three enzymatic activities: serine protease, NTPase and RNA helicase. NS4A is a cofactor for the NS3 protease activity (By similarity). RNA-directed RNA polymerase NS5 replicates the viral (+) and (-) genome. See Also Helicase 3D structures
