Figure 1From: Iteration method for predicting essential proteins based on orthology and protein-protein interaction networksCumulative percentage of essential proteins in orthologs sets. Figure1 shows the percentages of essential proteins out of the proteins that have orthologs in 99 reference organisms not less than number ep of times. It illustrates the relationship between the essentiality properties of proteins and the number of orthologs that they have in reference organisms.Back to article page
