Figure 2From: Systematic approach to Escherichia coli cell population control using a genetic lysis circuitInducible LuxR-regulated circuit with lysis gene in E. coli. A constitutive promoter continuously produces the activator protein LuxR. The protein LuxR needs to form a complex with the inducer AHL. The LuxR-AHL complex constitutes a quorum sensing mechanism. It activates the downstream promoter and enhances expression of the lysis gene when this complex accumulates.Back to article page
