Model in which protein decreases the association rate of protein . and from bottom to top curve.

<p>A) . Solid lines are for protein , the dotted line is for protein . The grey line is a monoexponential fit. The dashed lines are used for estimating the rate constants from the curves, giving . After has risen to a high level, recruitment of becomes much slower, and the slope of the recruitment curve of (purple curve) decreases faster than would be expected from a monoexponential curve that has a similar initial slope (grey curve). B) same parameters as in A) except . The curves always resemble a monoexponential function.
