Chemical reactions in the PhoBR E. coli stochastic kinetic model [15].

Reactions included in the KZW stochastic model [15], together with the associated propensity functions and values of the stochastic rate constants. Values given are for the autoregulated, slow transcription case. The value of varies with the external signal in our simulations. d-mRNA-RR, d-RR, d-mRNA-HK, d-HK, d-mRNA-Rep and d-Rep are degradation products of mRNA-RR, RR, mRNA-HK, HK, mRNA-Rep and Rep respectively. prom-HK is the promoter region of the HK gene.
