Emergence of Elastic Properties in a Minimalist Resilin-Derived Heptapeptide upon Bromination

Andrea Pizzi et al. Small. 2022 Aug.

Abstract

Bromination is herein exploited to promote the emergence of elastic behavior in a short peptide-SDSYGAP-derived from resilin, a rubber-like protein exerting its role in the jumping and flight systems of insects. Elastic and resilient hydrogels are obtained, which also show self-healing behavior, thanks to the promoted non-covalent interactions that limit deformations and contribute to the structural recovery of the peptide-based hydrogel. In particular, halogen bonds may stabilize the β-sheet organization working as non-covalent cross-links between nearby peptide strands. Importantly, the unmodified peptide (i.e., wild type) does not show such properties. Thus, SDSY(3,5-Br)GAP is a novel minimalist peptide elastomer.

Keywords: bromination; elastomers; halogen bonding; peptides; resilin; self-assembly; supramolecular chemistry.
