Abstract
The complete DNA sequence of the 10–45 kbp HindIII B fragment of bovine herpesvirus type 4 (BoHV-4) was determined. This fragment contains nine complete and two incomplete open reading frames (ORFs), all of which are homologous to herpesvirus saimiri (HVS), Kaposi's Sarcoma-associated herpesvirus (HHV-8) and Epstein-Barr virus (EBV). Particularly, the arrangement of the gene for the terminase-related protein with the two coding exons 29a/29b is conserved among all herpesviruses sequenced to date. The intron carries the ORFs 30 to 33 in the opposite direction. Analysis by reverse transcription and polymerase chain reaction (PCR) of the transcript across the proposed splice junction of the ORF 29a/29b and subsequent sequence determination of the amplified product revealed the precise structure of the splice junction. Furthermore, the phylogenetic analysis of the 29a/29b protein and its counterparts in other herpesviruses revealed that BoHV-4 clustered in the genus Rhadinovirus of the subfamily Gammaherpesvirinae.
