Stapling of a 3<sub>10</sub>-Helix with Click Chemistry
short peptides that has shown promise when applied to 310- and α-helical peptides. However, atomic resolution structural information on the effect of side chain-to-side chain cyclization in 310-helical peptides is scarce, and reported data suggest that there is significant potential for improvement of existing methodologies. Here, we report a novel stapling methodology for 310-helical peptides using

Two helical peptides, one constrained by a covalent side-chain staple, exhibit vastly different electronic properties despite adopting essentially the same backbone conformation. High level calculations confirm that these differences are due to the additional backbone rigidity imparted by the macrocyclic constraint.
