Features of Reovirus Outer-Capsid Protein mu1 Revealed by Electron and Image Reconstruction of the virion at 7.0-A Resolution
|
OverviewOverview
Reovirus is a useful model for addressing the molecular basis of membrane, penetration by one of the larger nonenveloped animal viruses. We now, report the structure of the reovirus virion at approximately 7.0 A, resolution as obtained by electron cryomicroscopy and three-dimensional, image reconstruction. Several features of the myristoylated outer capsid, protein mu1, not seen in a previous X-ray crystal structure of the, mu1-sigma3 heterohexamer, are evident in the virion. These features appear, to be important for stabilizing the outer capsid, regulating the, conformational changes in mu1 that accompany perforation of target, membranes, and contributing directly to membrane penetration during cell, entry.
