List of chemical reactions in stochastic simulations and reaction rates.

The network schemes in Fig 1A can be simulated by including the reactions with black squares for (i) constitutive expression, (ii) constitutive repressor, (iii) autoregulated repressor and (iv) bicistronic autoregulation. Rates fixed in all simulations (when not set to zero) are listed below along with names of variable reaction rates. The number of free inducer molecules was kept constant.
