Reversible redox reconfiguration of secondary structures in a designed peptide

Research output: Contribution to journalArticlepeer-review


Secondary structures are critical regulators of protein structure and function. Switchable peptides that can adopt multiple defined conformations in response to stimuli are attractive model systems for the study of protein folding and misfolding. A peptide is presented that can be reversibly reconfigured between an α-helical monomer and a β-sheet aggregate upon one-electron oxidation and reduction in the presence of Cu I/CuII.
