Physiology and Emerging Biochemistry of the Glucagon-Like Peptide-1 Receptor

Figure 2

Structure of the GLP-1 receptor ectodomain. The overall structure of the GLP-1 receptor ectodomain is depicted (PDB ID: 3IOL) [74]. The tripartite α-β-βα structure is annotated using color; from N-terminal to C-terminal α (blue), β (green), βα (yellow). The three conserved disulfide bonds that stabilize the tertiary structure of the ectodomain are colored in red.
