Gene network models of the effects of downstream genes. (a) The reporter-less model. (b) The reporter-containing model. AraC and LacI form positive and negative feedback loops, respectively. GFP is the downstream gene of this oscillator. ClpXP is the protease that recognizes and cleaves the SsrA-tagged proteins (AraC, LacI, and GFP).
