XbaI, PstI, and BglII restriction enzyme maps of the two orientations of the varicella-zoster virus genome.
Cleavage of varicella-zoster virus DNA with the restriction endonucleases PstI, XbaI, and BglII resulted in 18, 22, and 20 fragments, respectively. Based on the molecular weights and molarities of these fragments, a molecular weight of 84 x 10(6) could be calculated for the varicella-zoster virus genome. In both the XbaI and the BglII patterns, four 0.5 M fragments were identified. The arrangement of the fragments was determined by molecular hybridization techniques, and the terminal fragments were identified by lambda exonuclease digestion. The 0.5 M fragments, of which two were located at the same terminus of the genome, contained repeated sequences: one terminally and one inverted internally. These results were in agreement with the existence of two equimolar subpopulations of the varicella-zoster virus genome, differing in the relative orientation of a short region of unique sequences. This region was bounded by the repeated sequences. From the molecular weights of the submolar fragments, a maximal molecular weight of 5 x 10(6) for the repeated region and a minimal molecular weight of 3.5 x 10(6) for the short unique sequence could be calculated.
