T=7 icosahedral capsid protein (kw:KW-1145)


image The capsid is composed 60 asymmetric units made of 7 proteins (T=7), for a total of 420 capsid proteins. These capsids are skewed and are therefore referred to as either right-handed (dextro) or left-handed (laevo).

Papillomaviruses and Polyomaviruses are composed solely of pentameric capsomeres for a total of 360 capsid proteins. Nevertheless their icosahedral structure is that of a T=7 capsid in which pentamers occupy hexavalent positions.
