Abstract: Encapsidation of simian virus 40 is a complex biological process involving DNA-protein and protein-protein interactions in the formation of a unique three-dimensional structure around the viral minichromosome. A pseudoviral system developed in our laboratory, in which the viral early and late gene products are supplied in trans (by helpers), was used to analyze the encapsidation process independent of viral gene expression. With this experimental system we have discovered a requirement for a specific DNA signa…
