Movie S1 3-D reconstruction of Ebola virus nucleocapsid. This movie shows the three-dimensional structure of the of the Ebola virus nucleocapsid as shaded surface representation. The surface is set at a density threshold which would include one copy of NP, VP24,VP30, VP35, and the RNA. The nucleocapsid rotates, and then is sliced through the Z-axis to show the internal components of the structure. Movie S3 Ebola virus spike distribution. This movie shows one surface of a cryo-electron tomogram of an Ebola viruslike particle, generated by expressing the VP40 and GP proteins. The structure rotates showing the distribution of spikes. The locations of individual spikes are identified by white spheres, and the reconstruction is replaced by a cylinder to show the patchy distribution of spikes on the surface of the virus-like particle.
