Comments "Two-component systems are a common sensing motif in bacteria that connect environmental signals to changes in gene expression (Beier and Gross, 2006 Majdalani and Gottesman, 2005). Bacteria have multiple two-component systems, many of which operate simultaneously (Escherichia coli has ~32) (primary source)."
