Abstract

Abstract : Supramolecular Chemistry In article number 2200807, Pierangelo Metrangolo and co‐workers report the emergence of elasticity in a short peptide sequence—SDSYGAP—derived from resilin, upon bromination of the tyrosine residue. Bromine‐mediated halogen bonds act as non‐covalent crosslinks between nearby peptide strands, favoring the formation of elastic hydrogels in which such crosslinking points limit deformations and contribute to structural recovery of the peptide‐network.
