Influence of an inhibitory binding competitor. (A) Target site search time τ of the gene and (B) probability p of the promoter to be occupied by a TF (occupation frequency) as function of the unspecific dissociation rate constant ζ1 of the competitor. (C) τ and (D) p as function of the specific dissociation rate constant ζ of the competitor. Simulation parameters are: N = 100, C = 100, B = 104, λ10 = Λ10 = 4·10−4 s−1, λ0 = Λ0 = 10−5 s−1, λ2 = Λ2 = 4 s−1, μ = 10−1 s−1, ζ = 10−3 s−1.
