CRYSTAL STRUCTURE OF THE TOP DOMAIN OF AFRICAN HORSE SICKNESS VIRUS VP7CRYSTAL STRUCTURE OF THE TOP DOMAIN OF AFRICAN HORSE SICKNESS VIRUS VP7
Structural highlights
Function[VP7_AHSV4] Major structural core protein; binds to structural protein VP3. Constitutes the surface of the AHSV core. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe baculovirus-expressed core protein VP7 of African horse sickness virus serotype 4 (AHSV-4) has been purified to homogeneity and crystallized in the presence of 2.8 M urea. The X-ray structure has been solved to a 2.3-Angstroms (1 Angstrom = 0.1 nm) resolution with an Rfactor of 19.8%. The structure of AHSV VP7 reveals that during crystallization, the two-domain protein is cleaved and only the top domain remains. A similar problem was encountered previously with bluetongue virus (BTV) VP7 (whose structure has been reported), showing that the connections between the top and the bottom domains are rather weak for these two distinct orbiviruses. The top domains of both BTV and AHSV VP7 are trimeric and structurally very similar. The electron density maps show that they both possess an extra electron density feature along their molecular threefold axes, which is most likely due to an unidentified ion. The characteristics of the molecular surface of BTV and AHSV VP7 suggest why AHSV VP7 is much less soluble than BTV VP7 and indicate the possibility of attachment to the cell via attachment of an Arg-Gly-Asp (RGD) motif in the top domain of VP7 to a cellular integrin for both of these orbiviruses.
