Description: Caption:
This illustration provides a 3-dimensional (3D) graphical representation of a tightly packed, icosahedral, poliovirus particle that consists of 60-copies each of capsid polypeptides, designated as pink VP1 (viral protein1), green VP2, purple VP3, and though not shown here, VP4. This particle was composed of units of four capsid polypeptides, which interact in groups of five, resulting in a viral particle that has, what is referred to as 5-fold (pentameric), and 12-fold symmetry. Note the deep canyon on the capsid’s surface surrounding the apex of each pentamer of the virus. The canyon, together with the pentamer apex, is used as the site for capsid binding to cellular receptors.
