Peptide stapling is a macrocyclization strategy used to constrain short peptides, typically into an α-helical conformation. By introducing a chemical brace, the peptide is locked into a bioactive shape that is significantly more stable than its linear counterpart.
For example, the SP9 is Metal Ion-Peptide Interactions in the Gas Phase: A Tandem a hydrocarbon-stapled peptide that demonstrates how structural rigidity can enhance functionality. In the context of material binding, this rigidity ensures that the binding site remains exposed and ready to interact with the metal lattice, providing a consistent "lock-and-key" fit on the surface.
