Co-conservation of chemotaxis and flagellar proteins. (a) E. coli K12; (b) S. typhimurium LT2; (c) across multiple species. Proteins are color coded base on function: chemotaxis, pink; biofilm, light blue; flagellar, light red; type III secretion, blue; and sigma factor and regulation, yellow. The gray proteins are Bacillus sigma factor and regulation that are co-conserved but were not identified by single species CC analysis. Edge color code: E. coli K12, green; E. coli O157, blue; Shigella flexneri, black; S. typhimurium LT2, purple; P. aeruginosa, mustard; and Bacillus subtilis, red.
