Development of genetic circuitry exhibiting toggle switch or oscillatory behavior in Escherichia coli.

Abstract excerpt

Analysis of the system design principles of signaling systems requires model systems where all components and regulatory interactions are known. Components of the Lac and Ntr systems were used to construct genetic circuits that display toggle switch or oscillatory behavior. Both devices contain an "activator module" consisting of a modified glnA promoter with lac operators, driving the expression of the...
