== Publication Abstract from PubMed == | |||
Avian reovirus fibre, a homo-trimer of the sigmaC protein, is a minor component of the avian reovirus outer capsid. It is anchored via a short N-terminal sequence to the inner capsid lambdaC pentamer, and its protruding globular C-terminal domain is responsible for primary host cell attachment. We have previously solved the structure of a receptor-binding fragment in which residues 160-191 form a triple beta-spiral and 196-326 a beta-barrel head domain. Here we have expressed, purified and crystallized a major sigmaC fragment comprising residues 117-326. Its structure, which was solved by molecular replacement using the previously determined receptor-binding domain structure and refined to 1.75 A (0.175 nm) resolution, reveals an alpha-helical triple coiled-coil connected to the previously solved structure by a zinc-ion-containing linker. The coiled-coil domain contains two chloride ion binding sites, as well as specific trimerization and registration sequences. The linker may act as a functionally important hinge. | |||
