REOVIRUS POLYMERASE LAMBDA-3 LOCALIZED BY ELECTRON CRYOMICROSCOPY OF VIRIONS AT 7.6-A RESOLUTION
Overview
Reovirus is an icosahedral, double-stranded (ds) RNA virus that uses viral polymerases packaged within the viral core to transcribe its ten distinct plus-strand RNAs. To localize these polymerases, the structure of the reovirion was refined to a resolution of 7.6 A by cryo-electron microscopy (cryo-EM) and three-dimensional (3D) image reconstruction. X-ray crystal models of reovirus proteins, including polymerase lambda 3, were then fitted into the density map. Each copy of lambda 3 was found anchored to the inner surface of the icosahedral core shell, making major contacts with three molecules of shell protein lambda 1 and overlapping, but not centering on, a five-fold axis. The overlap explains why only one copy of lambda 3 is bound per vertex. lambda 3 is furthermore oriented with its transcript exit channel facing a small channel through the lambda 1 shell, suggesting how the nascent RNA is passed into the large external cavity of the pentameric capping enzyme complex formed by protein lambda 2.
