Abstract
The nucleotide sequences of the termini of the mature pseudorabies virus genome and of the junction between these termini in concatemeric DNA were compared. To ensure conservation of unmodified 5' and 3' termini, the end fragments obtained directly (uncloned) from mature viral DNA were sequenced. The sequence obtained from 5' and 3' end labeling revealed that whereas the L terminus was blunt ended, the S terminus had a 2-base (GG) 3' overhang. The sequences spanning the junction between the termini present in concatemeric DNA was also determined and compared with that expected when the two ends of the mature DNA were juxtaposed. This comparison showed that in concatemeric DNA the ends of the mature genome had become joined by blunt-end ligation of one of the strands and that the 2-nucleotide gap on the other strand had been repaired. A significant degree of homology between the sequences spanning the junction between the ends of the varicella-zoster virus and pseudorabies virus genomes was found.
