Peptide stapling provides control over conformation leading to improved stability and enhanced binding affinity. Non-symmetric stapling is more broadly applicable but introduces a requirement for high chemo-selectivity and site-selectivity. The image shows one such unsymmetrically stapled peptide binding to its target — image generated from Baeriswyl, S., Stocker, A., Reymond, J.-L., Fucosylated bicyclic peptide bp71 bound to the fucose binding lectin LecB PA-IIL from Pseudomonas aeruginosa at 1.7 Angstrom resolution (2020) https://doi.org/10.2210/pdb6y0v/pdb (PDB ID 6Y0V). The past 5 years have witnessed several significant breakthroughs in addressing these challenges and are the subject of a review by Chen et al.
