FIG 3.
Alignment of N-terminal sequences of UL51 homologs from human herpesviruses. Homologs of UL51 from all herpesviruses for which sequences are available were aligned by using the MUSCLE sequence alignment program (52). The alignment from the N terminus of the human herpesvirus homologs is shown. The positions of the conserved cysteine residue that is the palmitoylation site (26) and of the conserved YXXΦ motif are boxed. VZV, varicella-zoster virus; Kaposi's sarcoma-associated herpesvirus; HHV6, human herpesvirus 6.
