Figure 1<br />

Schematic illustration of the icosahedral rhinovirus 14.<br />

(a) Shown is the icosahedron comprised of 60 copies<br />

each of VP1 (light gray), VP2 (black), and VP3 (gray).<br />

The shaded circles around each five-fold axis indicate<br />

the canyon positions. Also indicated is the approximate<br />

position of the VP1 hydrophobic pocket that lies<br />

underneath the surface of the virion. (b) An<br />

icosahedral pentamer is expanded with one viral protomer<br />

shown as a protein ribbon diagram. (c) This pentamer is<br />

seen in a cutaway view. Here VP1 is white, VP2 and VP4<br />

black, and VP3 gray. A capsid-binding compound is<br />

depicted as black spheres inside the VP1 ribbon diagram.<br />

The cross hatched regions on the (c) schematic (right)<br />

indicate areas that disorder when HRV14 crystals are<br />

exposed to acid.<br />
