Comparisons of the predicted parameters of Hill function for gene induction mediated by two competing factors (A+R).

(a)PsAct: The transcriptionally active promoter is defined by only activator-bound state.
(b)PsAct+PsUnb: The transcriptionally active promoter is defined by both unbound and activator-bound states that are the summation of constitutively and fully expressed gene.
(c)Our method reported in this paper.
(d)Addition (1.6+1.8) or multiplication (1.6×1.8) as reported in Rossi et al. (2000).
(e)An experimentally observed value reported in Rossi et al. (2000).
