Ligands: CL, GOL Activity: Flavivirin, with EC number 3.4.21.91 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [Q91H74_9FLAV] Envelope protein E binding to host cell surface receptor is followed by virus internalization through clathrin-mediated endocytosis. Envelope protein E is subsequently involved in membrane fusion between virion and host late endosomes. Synthesized as a homodimer with prM which acts as a chaperone for envelope protein E. After cleavage of prM, envelope protein E dissociate from small envelope protein M and homodimerizes (By similarity).[SAAS:SAAS026470_004_099774] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed 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.
