  1. Parameters correspond to the simulations of Fig. 1a. We use realistic enzyme kinetic parameters49 and fast promoter switching according to measured ranges56. The dilution rate constant ή corresponds to a doubling rate of approximately 46 min, typical in the Escherichia coli bacterium. The distributions in Fig. 1c were obtained with perturbed promoter switching parameters kon = 0.01 s−1 and koff = {0.03, 0.01, 0.0001} s−1. The parameter values for Figs. 2 and 3 are shown in the respective captions
