Sequence alignment of alpha-, beta-, and gammaherpesvirus UL37 proteins. Sequence alignment of HSV-1, HSV-2, HCMV, and EBV UL37 proteins was performed as described in Materials and Methods. The region is similar to the aa 470-to-485 codon region of Fig. 1. The consensus sequence logo depicts the relative conservation of each residue. Orange highlights conserved proline, and yellow highlights conserved phenylalanine. The region Y551-Y557 corresponding to Y474-Y480 shown in Fig. 1 is highlighted in blue.
