Herpesvirus papio DNA is similar in organization to Epstein-Barr virus DNA

Abstract

EcoRI, HindII, SalI, nd XbaI restriction endonuclease maps of herpesvirus papio (HVPapio) DNA were derived by determining the fragment sizes and the linkage relationships between fragments generated by the different enzymes. The data indicate that HVPapio DNA has a single molecular arrangement which is similar to that of Epstein-Barr virus DNA. The size of the DNA was 110 X 10(6) to 114 X 10(6) daltons. Restriction fragments from both ends varied in the number of repeats of a 4 X 10(5)-dalton sequence, TR, and hybridized to each other. This suggests that there is an identical repeating unit, TR, at both ends of the DNA. There were usually six tandem repetitions (range, 1 to 11) of a 2 X 10(6)-dalton sequence, IR, within the DNA. IR separated the DNA into two domains of largely unique sequence complexity, a 9 X 10(6)-dalton segment, Us, and an 88 X 10(6)-dalton segment, UL. There was homology between DNA fragments which mapped at 25 X 10(6) to 29 X 10(6) to 91 X 10(6) to 95 X 10(6) daltons in UL.
