Early events in the infection of permissive cells with simian virus 40: adsorption, penetration, and uncoating

G Barbanti-Brodano et al. J Virol. 1970 Jul.

Abstract

The early events in the interaction of simian virus 40 (SV40) with permissive cells were investigated. Evidence is presented that 30 min after infection intact virions penetrate the nuclei of infected cells. The uncoating of the virus is carried out in the nuclei with a complete dissociation of the viral genome from the protein coat. Opening of the circular parental deoxyribonucleic acid (DNA), i.e., conversion of component I to component II of SV40 DNA, takes place after uncoating, followed by the appearance of a new component sedimenting faster than component I at alkaline pH.
