Stereo view of the electron density maps of Aura virus (red) and SINV (blue), displayed at a high contour level, with the capsid appearing at the bottom and the glycoprotein at the top. The finger-like projections pointing downwards from the glycoproteins and upward from the capsid, and corresponding to the transmembrane densities of Aura and SINV, are indistinguishable at the upper surface of the membrane but have slightly different orientations at the lower surface.
