b and Y (5 mM) are experimentally determined values corresponding to the normalized protein levels at 0 mM and 5 mM theophylline, respectively. The EC50 and theoretical maximal output (M) are parameters determined by fitting the dose-response data to the binding model. The fold-change is the ratio of Y (5 mM) to b and the dynamic range is the difference between these two values. The theoretical fold-change and dynamic range determined by M instead of Y (5 mM) are reported in Supplementary Table S2.
