Fig. 6. The steady-state ligand occupancy (open symbols) and fractional population (filled symbols) for each methylation state at different ambient ligand concentration for Tar receptors. The thick line is the total ligand occupancy for Tar; it is constant for a large range of MeAsp concentrations due to perfect adaptation and the fact that the activity of Tar is determined by its ligand-binding status for m > 0 in our wild-type model.
