Structures of the HSV-1 portal (a) and CCSC (b). In (a), the structure of the HSV-1 portal is shown beside the portals of phages T7 and P22 [8, 48–49]. Note that the three are similar in size and structure suggesting their function is the same. All are cylindrical in shape with 12-fold rotational symmetry and an axial channel through which virus DNA enters and exits the capsid. In (b) the CCSC is highlighted in green and shown in the full capsid (left) and at higher magnification in a single vertex (right). Note that five CCSC rods project radially outward from each capsid vertex. CCSC graphic courtesy of James Conway (University of Pittsburgh; [25]).
