FIG. 6.

Integrin ring in association with the Ad12 capsid. (A) Side- and top-surface views. (B) Slice planes through the integrin density perpendicular to an icosahedral fivefold symmetry axis. The heights of the slice planes are indicated by numbered lines in panel A. The color scheme for the individual proteins is as shown in Fig. 4B. Stronger density values are represented by darker shades, and weaker density values are represented by lighter shades. The black lines in slice 3 designate the boundary for the extracted model of one integrin proximal domain displayed in Fig. 7. The scale bars are 100 Å.
