Modelling and Simulation


Our model involves both activation and repression systems. Activation of asr promoter in acidic medium results in production of GFP and tetR proteins. Increasing tetR in the system results in repression of tet promoter and hence reduction in the production of RFP.




Rates of formation of the above mentioned proteins can directly be related to the respective respressor/activator by using Hill’s function.
Rate of production of protein Y = f(X*), where f is an input Hill function, and X* is the active form of activator/repressor X.




The Hill parameters are β, K and n.
β: Maximal rate of expression of protein.
K (Activation coefficient): Concentration of X* that is needed to significantly activate expression of Y.
n (Cooperativity coefficient): Determined by the binding cooperativity of active for of repressor/activator to the binding site on promoter.
