Structural ensembles calculated for the wild-type capsid (CAFL) dimer (A) and monomer (B). In panels A and B the C-terminal domain is displayed as light gray ribbons. In panel B the C-terminal domain of the monomer is displayed in the same orientation as that of the A subunit in panel B. The overall distribution of the N-terminal domain relative to the C-terminal domain is displayed as a reweighted atomic probability [40] plotted at 50% (blue) and 10% (transparent red) of maximum. Additionally, a single complete monomer structure is plotted in panel B (with the N-terminal domain depicted in green) which corresponds to one cluster of ensemble members which form transient contacts in the monomer and would be occluded in the dimer ensemble.
