To this end, the protein accession numbers (or GI numbers) were queried from the Ingenuity database. For the purpose of this figure, all known functions associated with these proteins were exported to Microsoft Excel and regrouped. In the top pie chart, the cellular proteins found in all the herpesvirions were analyzed collectively, while the other pie charts depict the host proteins incorporated into each virus. Since each protein can be associated with multiples functions in the database, the results of those analyses are expressed as relative values instead of raw numbers, which consequently exceeds the original number of proteins analyzed. The percentages therefore represent the number of proteins falling into a given category with the total of each pie chart being 100%. A graphical legend of the categories is provided at the bottom right corner of the figure.
