Fig. 1. Variability of the pol sequence among HHV-6 strains. Nucleotide sequencing was carried out on DNA amplified from HHV-6-infected cell cultures. The consensus HHV-6 variant A sequence (HHV-6 A cs) was established from the pol sequences of SIE, U1102 and TAN strains. The consensus HHV-6 variant B sequence (HHV-6 B cs) was established from the pol sequences of BLA, BLE, BOB, BOU, MAR, MBE and TRA strains. Dashes indicate identical amino acid residues in HHV-6 A cs and HHV-6 B cs. The open and closed circles correspond to the positions of amino acid residues that vary between variants A and B, respectively. The arrow indicates the position of the amino acid residue specifically modified in the case of GCVR1 HST.
