G-Protein-Coupled Receptors (PDB entries 1f88, 3eml, 2vt4, 2rh1, 3odu, 3pbl, 3rze, 4djh, 4dkl, 4ea3 & 3v2y)
Eleven different GPCR structures are superimposed in this Jmol. As you flip through the structures, notice the similarity in the membrane-spanning helices (shown in pink), and the diversity in the second extracellular loop (in bright green). In each case, the ligand is shown in spacefilling representation with atomic colors.
