T=25 icosahedral capsid protein (kw:KW-1148)


image The capsid is composed 60 asymmetric units made of 25 proteins (T=25), for a total of 1500 capsid proteins.

Icosahedric triangulation number is calculated following Caspar and Klug system


Adenoviridae and Tectiviridae capsid symmetry is a pseudo T=25 structure, because hexamers are formed by 3 subunits instead of 6.
