Sequence comparison of the HSV-1 scaffold region involved in UL6 interaction with similar regions in 10 other alphaherpesviruses. The comparison revealed a site of sequence homology within the putative UL6 binding domain, corresponding to aa 144 to 148 of the HSV-1 scaffold. CHV, cercopithecine herpesvirus; BHV, bovine herpesvirus; SMHV, squirrel monkey herpesvirus; GHV, gallid herpesvirus; EHV, equine herpesvirus; VZV, varicella-zoster virus.
