    • The gene circuit shown in Fig. 1B can be described, in a continuous approximation, by two coupled differential equations that govern the dynamical evolution of the concentrations of ComK and ComS proteins, denoted K and S, respectively. The equation for K is dK/dt, αk, βkKn/Kkn, Kn, δkK/1, K/Γs, λkK, where αk and βk parameterize the strength of constitutive and autoregulated ComK expression, respectively. The third term models degradation through competitive binding of ComK and ComS to MecA. The final term represents linear degradation of ComK. The equation for S is dS/dt, αs, βs/1, K/ksβ, δsS/1, K/Γs, λsS. Here, αs and βs measure the strength of constitutive and regulat
    • comp strongly constrains the allowed parameter values and thus the structure of the phase space. The modeling is described in detail in the SOM text.
