A comparative analysis of envelope and tegument proteins of suid herpesvirus 1, bovine herpesvirus 1 and bovine herpesvirus 5.

The aim of this study was to analyze the disordered regions (DRs) in the envelope and tegument proteins of three closely related herpesviruses: bovine herpesvirus 1, bovine herpesvirus 5 and suid herpesvirus 1. Tegument proteins showed a greater percentage of DRs than the envelope proteins did. Regions of disorder were found in the less conserved portions of the proteins, N-terminal and C-terminal regions, and, in a few cases, functionally important sites. The presence of DRs is an important factor in the evolution of viruses, representing points where positive pressure led to structural changes.
