Figure 11-4: The three-fold axes of symmetry of fX174 'closed' procapsid. In the native structure, the large coat helix does not sit occupy the three-fold axes of symmetry, which contain pores. The results of genetic analyses suggest interactions between the first α-helix of the D4 subunit and the large coat protein helix.
