Schematic Representation of Ligand Association to a Given G Protein-Coupled Receptor (Green Lines).
The ligand (orange spheres) makes an initial contact with the extracellular surface (light grey box) of the receptor at the so-called extracellular vestibule to form a metastable intermediate conformation. Substantial desolvation (water molecules, blue spheres) takes place at this step, representing a major energetic barrier to binding. Afterwards, the ligand enters into the orthosteric binding site (dark grey box) with a relatively fast speed.
