The hexameric capsomeres are formed by the B and C subunits. The N-terminus arms (residue 27 through 49) of the subunits intertwine to form a ring structure. The N-terminus is therefore key to the hexamer composition. | The hexameric capsomeres are formed by the B and C subunits.

Each hexamer consists of six beta strands that run parallel to each other and result in a pore in the center of the hexamer. Residues 29-33 line this pore and cover the opening of the capsid by the interaction of their side chains with adjacent residues. For example, the "side chain oxygens of Gln29 residues hydrogen bond with the main chain nitrogens of adjacent Gln29 residues, making a circular ring of interactions." | |||

Pentamer capsomeres, on the other hand, are formed exclusively from the contribution of A subunit chains. | Pentamer capsomeres, on the other hand, are formed exclusively from the contribution of A subunit chains. | ||
