We have determined the DNA sequence of the long unique region (UL) in the genome of herpes simplex virus type 1 (HSV-1) strain 17. The UL sequence contained 107,943 residues and had a base composition of 66.9% G + C. Together with our previous work, this completes the sequence of HSV-1 DNA, giving a total genome length of 152,260 residues of base(More)
We have determined the complete DNA sequence of the short unique region in the genome of herpes simplex virus type 1, strain 17, and have interpreted it in terms of messenger RNAs and encoded proteins. The sequence contains variable regions whose length differs between DNA clones. The clones used for most of the analysis gave a short unique length of 12,979(More)
The taxonomy of herpesviruses has been updated by the International Committee on Taxonomy of Viruses (ICTV). The former family Herpesviridae has been split into three families, which have been incorporated into the new order Herpesvirales. The revised family Herpesviridae retains the mammal, bird and reptile viruses, the new family Alloherpesviridae(More)
Herpesviruses comprise an abundant, widely distributed group of large DNA viruses of humans and other vertebrates, and overall are among the most extensively studied large DNA viruses. Many herpesvirus genome sequences have been determined, and interpreted in terms of gene contents to give detailed views of both ubiquitous and lineage-specific functions.(More)
The genomes of herpes simplex virus type 1 (HSV-1) and varicella-zoster virus (VZV) consist of two covalently joined segments, L and S. Each segment comprises an unique sequence flanked by inverted repeats. We have reported previously the DNA sequences of the S segments in these two genomes, and have identified protein-coding regions therein. In HSV-1, the(More)
The genetic content of wild-type human cytomegalovirus was investigated by sequencing the 235 645 bp genome of a low passage strain (Merlin). Substantial regions of the genome (genes RL1-UL11, UL105-UL112 and UL120-UL150) were also sequenced in several other strains, including two that had not been passaged in cell culture. Comparative analyses, which(More)
The genomic DNA sequence of herpes simplex virus type 2 (HSV-2) strain HG52 was determined as 154,746 bp with a G+C content of 70.4%. A total of 74 genes encoding distinct proteins was identified; three of these were each present in two copies, within major repeat elements of the genome. The HSV-2 gene set corresponds closely with that of HSV-1, and the(More)
A detailed phylogenetic analysis for mammalian members of the family Herpesviridae, based on molecular sequences is reported. Sets of encoded amino acid sequences were collected for eight well conserved genes that are common to mammalian herpesviruses. Phylogenetic trees were inferred from alignments of these sequence sets using both maximum parsimony and(More)
With the aim of deriving a definitive phylogenetic tree for as many mammalian and avian herpesvirus species as possible, alignments were made of amino acid sequences from eight conserved and ubiquitously present genes of herpesviruses, with 48 virus species each represented by at least one gene. Phylogenetic trees for both single-gene and concatenated(More)
Amino acid sequence comparisons show extensive similarities among the deoxyuridine triphosphatases (dUTPases) of Escherichia coli and of herpesviruses, and the 'protease-like' or 'pseudoprotease' sequences encoded by certain retroviruses in the oncovirus and lentivirus families and by poxviruses. These relationships suggest strongly that the(More)
