Figure 3. Weighted activity profiles for inactivation of a protein by a factor α < 1 with each successive phosphorylation.
We plot Xa/XT as a function of k/h, as given by Eq. (6) for an ordered distributive mechanism (A) and by Eq. (7) for a disordered distributive mechanism (B). In either case, N = 10 and α is given the value in the circle superimposed on each curve.
