    In nature, proteins serve as media for long‐distance electron transfer (ET) to carry out redox reactions in distant compartments. This ET occurs either by a single‐step superexchange or through a multi‐step charge hopping process, which uses side chains of amino acids as stepping stones. In this study we demonstrate that Phe can act as a relay amino acid for long‐distance electron...

    The search for relay stations. Long-distance electron transfer in peptides

    Bernd, Giese ; Kracht, Sonja ; Cordes, Meike

    In: CHIMIA International Journal for Chemistry, 2013, vol. 67, no. 12, p. 855–858

    Nature uses peptide aggregates as soft materials for electron transfer over long distances. These reactions occur in a multistep hopping reaction with various functional groups as relay stations that are located in the side chain and in the backbone of the peptides.
