(A) Central sections through icosahedrally symmetrized ϕ6 procapsids obtained by single particle analysis (Sen et al., 2008; left) and from averaged tomograms (right). White arrows: P2; black arrows: P4; white arrowhead: central diffuse density. (B) Isosurface representations of the procapsids in (A) segmented into the different protein components, showing the P1 shell in grey and the P4 hexamers in red. (C) Same as (B) but cut through the center to show the P2 monomers in yellow. (The thresholds for the P2 and P4 densities were adjusted to approximately match the P1 shell). The single particle reconstruction was normalized to have the same reciprocal space amplitude profile as the tomographic average map, and band-limited to the same resolution (37 Å). Bar: 100 Å.
