Design of Redox-Active Peptides: Towards Functional Materials

Prior research has shown that electron and proton transfer processes are central to cellular metabolism. These processes involve changes in redox states of substrates, enabling biochemical reactions. A well-known example is the electron transport chain, which includes oxidoreductase proteins that move electrons and protons across membranes. Iron sulfur clusters and porphyrin-like molecules are commonly found in these systems. These cofactors have been studied in natural proteins such as those in photosynthesis and soluble electron carriers. An extensive literature has emerged focusing on modeling these cofactors in synthetic systems. Researchers have aimed to replicate natural electron transfer mechanisms in artificial materials. This work has led to the development of peptide-based systems that mimic biological electron transfer processes.
