We studied the activation of β2-adrenergic receptor(β2 AR) by norepinephrine,epinephrine and isoproterenol using docking and molecular dynamics(MD) simulation.The simulation was done on the assumption that β2 AR was surrounded with explicit water and infinite lipid bilayer membrane at body temperature.So the result should be close to that under the physiological conditions.We calculated the structure of binding sites in β2 AR for the three activators.We also simulated the change of the conformation of β2 AR in the transmembrane regions(TMs),in the molecular switches,and in the conserved DRY(Aspartic acid,Arginine and Tyrosine) motif.This study provides detailed information concerning the structure of β2 AR during activation process.
