Figure 4. Simulation of the sequestration mechanism.

A simulation of equations 1 and 2 illustrates the range of [dep]/K_d^probe and K_d^probe/K_d^dep over which pseudo-Hill coefficients above 2 (gray area) and above 4 (dark area) are obtained. Shown in boxes are some of the experimental pseudo-Hill coefficients we have observed (the horizontal and vertical lines of data were taken from figures 2 and 3 respectively).
