Figure 3. All docking results for possible unit cells composed of previously determined trimers.

Figure 3

For both HFBI and HFBII pentamers composed of trimers A and B, in each case the two trimers sharing a protein, could be constructed. These pentamers could not be docked to themselves thus they can not form a unit cell. For both HFBI and HFBII, hexamers could be constructed from two identical trimers, for HFBI from both trimer A and D (see figure 2), to form structures α and β, and for HFBII, from trimer A. In all three of these cases the hexamers could be successfully docked to themselves, as can be seen from the “18mers”, composed of three hexamers docked in a ring.
