[Pyr-1]-Apelin-13 is a pyroglutamyl-modified apelin ligand that enhances resistance to aminopeptidase degradation. Its structure preserves the C-terminal core required for receptor binding. The cyclic N-terminal residue influences peptide conformation and hydrophobic surface exposure. Researchers employ it to examine apelin signaling and ligand-receptor interface geometry.
