Recent advances in experimental proteomics have generated a wealth of data regarding proteins and protein-protein interactions in the native cellular environment. However, most proteomic analyses operate on a highly abstract level, treating proteins as nodes and protein-protein interactions as edges. Here, two studies are highlighted where three-dimensional modeling of protein networks within and between species provides insights into the biophysics and evolution of biological systems. First, a structural analysis of the yeast protein-protein interaction network reveals that protein evolution is constrained by the biophysics of protein folding, the mutational robustness of the native structure, and the biophysics and function of protein-protein interactions. Second, a structural analysis of human-virus proteinprotein
interaction networks reveals distinct principles governing antagonism versus cooperation in host-pathogen and within-host interactions.
