PG - 5597-604 AB - Determination of the nucleotide sequences of two molecular clones of human herpesvirus 6 (HHV-6) (strain GS) and comparison with those of human cytomegalovirus (HCMV) has allowed the identification of the genes for the glycoprotein H (gH) and the putative large tegument protein of HHV-6. Two molecular clones of fragments of HHV-6, the BamHI-G fragment (7,981 bp) of the clone termed pZVB43 and a HindIII fragment (8,717 bp) of the clone termed pZVH14, represent approximately 10% of the HHV-6 genome (16,689). An open reading frame within the BamHI-G fragment was designated the gH gene of HHV-6 because of the extensive sequence similarity of its predicted product (79,549 Da) to the HCMV gH gene product. The predicted product (239,589 Da) of an open reading frame within clone pZVH14 showed homology to the predicted product of the proposed gene of HCMV representing the large tegument protein. Computer analyses indicated a closer relationship of the predicted peptides of these HHV-6 genes to those of HCMV than to those of the other human herpesviruses Epstein-Barr virus, herpes simplex virus type 1, and varicella-zoster virus. The gH gene was more conserved among the human herpesvirus group, while significant sequence similarity of the tegument gene could be found only with that of HCMV. The data reported here with one conserved gene (gH) and a more divergent gene (tegument) support previous reports that HHV-6 and HCMV are more closely related to each other than to the other well-characterized human herpesviruses.
