Figure 1S. Forward and reverse primers for the mutants F222A and T235A.

Figure 2S. Root mean square fluctuations (rmsf) of Cα atoms, from an average structure computed from the last 25ns of the trajectories, were also calculated for the four trajectories.

Figure 3S. Definition of the dihedral angles of the antagonist NMS that were measured along the simulations.

Figure 4S. Values of the four dihedral angles of NMS measured in the different simulations: (a) POPC and (b) POPC/POPS.

Figure 5S. Representative Saturation Binding Curves of WT M3R and mutants F222A and T235A expressed in COS7 cells. The membranes were incubated with increasing concentrations of [3H] NMS in Hepes buffer at 30°C for about 2.5 hours. The protein concentration used was ca 10μg/mL. The specific and non-specific binding are expressed in fmol/mg protein.
