Ribbon diagram of β2-adrenergic receptor fusion protein with lysozyme (PDB code: 2RH1, light orange) superimposed on bovine rhodopsin (PDB code: 1U19, cyan). The fused T4 lysozyme to the β2-adrenergic receptor is shown in lemon. The bound ligand, carazolol, is shown in green sticks and the bound retinal in magenta sticks. The two classes of GPCRs share overlapping ligand-binding pockets.
