Figure 2. Model in which protein 
increases the association rate of protein 
. 
and 
from bottom to top curve.
A) 
. Solid lines are for protein 
, the dotted line is for protein 
, and the dashed lines are used for estimating the order of magnitude of the rate constants from the curves, giving 
for the steepest curve, and 
and 
for the slowest curve. Depending on the parameters the curves show an increasing slope at the beginning. B) same parameters as in A) except 
. The curves always show an increasing slope at the beginning, which helps distinguishing this case from the one shown in Figure 2A. Additionally, for large values of 
the recruitment curves of 
resemble the recruitment curve of 
, which is not the case if 
.
