In vitro DNA-packaging systems of bacteriophages T3 and T7 packaged homologous DNA more efficiently than heterologous DNA. Packaging of phage DNA proceeds by way of concatemeric intermediates (H. Fujisawa, J. Miyazaki, and T. Minagawa (1978), Virology 87, 394-400). The conversion of mature homologous and heterologous DNAs to concatemers was efficient in both the T3- and T7-packaging systems. In vitro complementation experiments indicate that the gene 19 product (gp19) specifies which DNA enters the capsid. To identify DNA regions recognized by the packaging systems, T3/T7 hybrids were constructed and physical maps of the hybrid DNAs were determined by restriction enzyme analysis. By comparing restriction maps and in vitro packaging of hybrid DNAs, it is concluded that the sequence responsible for specificity of DNA packaging is confined within 5% of the ends of the T3 and T7 genomes.
