The sequence of a 20.15 kb region from human herpesvirus 6 variant B (HHV-6B) strain Z29 is described (GenBank accession number L14772). Determinations of protein homologies for seventeen predicted gene products revealed HHV-6B homologs of six proteins well-conserved both in genetic context and amino acid sequence throughout the alpha-, beta-, and gammaherpesvirus subfamilies. These include proteins involved in viral DNA replication, packaging and nucleotide metabolism, and conserved proteins of undefined function. The close evolutionary relationship of the human betaherpesviruses, HHV-6B, HHV-6A, HHV-7 and human cytomegalovirus (HCMV) was confirmed by identification of several protein sequences encoded only by these viruses, including homologs of the HCMV early phosphoprotein family and a series of HCMV open reading frames predicted to encode glycoprotein exons. Homologs of essential HSV-1 replication proteins, UL8 and UL9, were also identified. Downstream from the conserved replication locus, each betaherpesvirus contains a region of divergent, small open reading frames. The evolution of this region and its potential use in the development of a viral vector system are discussed.
