Selected connected components of the E. coli gene network. Nodes correspond to gene sequences (blue for E. coli, green for all other bacteria, orange for archaea, and pink for mobile genetic elements). Edges were drawn when sequences showed an homology with a BLAST score < 1e-20, > 30% identity, option false BBH. Cytoscape was used for the display. (A) Putative homoserine kinase type II. (B) Translation Initiation Factor I. (C) Predicted permeases. (D) Type V secretory pathway proteins. (E) restriction endonuclease S subunit.
