Oscillation components in the time-course of the reporter-less model and the reporter-containing model by deterministic simulation. Oscillation components in the two models at 1.0% arabinose and 10 mM IPTG. AraC dimer (dark blue) in (a) the reporter-less model and (b) the reporter-containing model. AraC composition in the two models at 1.0% arabinose and 10 mM IPTG. AraC dimer (dark blue), AraC mRNA (light green), AraC unfolded polypeptides (deep green), AraC monomer (light blue), non-binding AraC promoter (red), and one AraC- binding AraC promoter (orange) in (c) the reporter-less model and (d) the reporter- containing model.
