Complete protein-protein networks of E. coli K12. Coverage and overlap are given in the central inset. Network proteins are color-coded based on the four KEGG functional categories: Unclassified (gray), Cellular processes (cyan), Environment information processing (blue), Genetic information processing (red), Metabolism (green) a) Gene cluster b) Gene neighbor c) Rosetta Stone d) Phylogenetic profile.
