GONUTS has been updated to MW1.31 Most things seem to be working but be sure to report problems.
Category:GO:0039618 ! T=pseudo3 icosahedral viral capsid
name: T=pseudo3 icosahedral viral capsid
namespace: cellular_component
def: "The protein coat that surrounds the infective nucleic acid in some virus particles where the subunits (capsomeres) are arranged to form an icosahedron with pseudo T=3 symmetry. The T=pseudo3 capsid is composed of 12 pentameric and 20 hexameric capsomeres." [VZ:809]
comment: T=pseudo3 capsids are not T=3 symmetry as described by Caspar and Klug (PMID:14019094) because the basic unit is composed of three different proteins. Since the three subunits are morphologically very similar, the structure is therefore a pseudo T=3.
