Definition
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. Source: VZ:809, UniProtKB-KW:KW-1143
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.
