  • a All ORFs and putative transcription signals are located at the reverse strand of the determined DNA sequence (GenBank accession no. AJ319028), and nucleotide positions (nt) are therefore numbered from right to left.

  • b The UL32 protein of PrV has not been identified.

  • c Values are percent similar residues (percent identical residues) and were determined using the Genetics Computer Group program “gap”. The amino acid sequences of the homologous alpha-, beta-, and gammaherpesvirus proteins were deduced from genomic DNA sequences (2, 12, 13, 33, 50).
