Bacteriophage P22 assembly pathway. Coat monomers, scaffolding protein, and portal monomers make up a nucleation complex, forming the portal ring around which the coat protein shell can be assembled by scaffolding protein. The ejection proteins are incorporated into the procapsid prior to DNA packaging by terminase proteins. Pressure from DNA induces a conformational change in the capsid and portal protein facilitating the dissociation of the terminase complex and addition of the tail machinery.
