Abstract:

The crystallographically determined structure of a soluble fragment from the major envelope protein of a flavivirus reveals an unusual architecture. The flat, elongated dimer extends in a direction that would be parallel to the viral membrane. Residues that influence binding of monoclonal antibodies lie on the outward-facing surface of the protein. The clustering of mutations that affect virulence in various flaviviruses indicates a possible receptor binding site and, together with other mutational and biochemical data, suggests a picture for the fusion-activating, conformational change triggered by low pH.
