Fig. 1.

Amino acid sequence alignment of the C-terminal regions of membrane protein UL56 and membrane protein UL56A from members of the subfamily Alphaherpesvirinae. The sequences are aligned only in the 15 residues at the left, as relationships among the sequences elsewhere are overall not detectable. The locations of PPXY (and related LPPY) motifs are highlighted in light grey, and other conserved residues located in or between the motifs are underlined. Additional PPXY and PPXY-related motifs in the N-terminal regions (indicated by >) are noted in square brackets. Predicted transmembrane domains are highlighted in dark grey. That for GaHV3 is in lower case to indicate that a correction of a putative frameshift (located approximately) was invoked. The total number of residues in each protein is indicated on the right.
