Figure 3.

Number of protein-protein interactions of prokaryotic and eukaryotic species. The total number of binary interactions (red circles) and the number of high confidence (score ≥ 900) interactions per protein (blue squares) was calculated for 16 prokaryotic and eukaryotic proteomes (see the 'Protein-protein interactions in different proteomes' section in Materials and methods), and are shown as a function of biological complexity.
