| - | made up from 3 proteins, 60 copies of each of '''VP0, VP1 and VP3''' (from proteolysis of polyprotein [https://www.uniprot.org/uniprotkb/P03300/entry UniProt P03300]). [[1pov]] provides the structure of the [[asymmetric unit]], with instructions for constructing the capsid ([[Biological Unit]] 1). | + | made up from 3 proteins, 60 copies of each of '''VP0, VP1 and VP3''' (from proteolysis of polyprotein [https://www.uniprot.org/uniprotkb/P03300/entry UniProt P03300]).

The polio capsid has an icosahedral construction with 12 vertices defining 20 triangular faces. Notice that the larger blue mesas protruding on the surface have 5-fold symmetry. These are pentagonal capsomeres at the 12 vertices. The capsid is composed of 180 protein chains totaling about 377K non-H atoms. | The polio capsid has an icosahedral construction with 12 vertices defining 20 triangular faces.
