The E. coli lac operon has been shown to display bistability after induction with the gratuitous inducers IPTG and TMG. The project aims at elucidating whether lactose can also evoke bistable expression of the lac operon. Possible benefits of such an induction patters are going to be investigated. In addition, the effect of the important intracellular second messanger cAMP in bistable gene expression will be analysed and we want to investigate if extracellular cAMP represents a signal at the population level.
