Proteins have long been involved in biological electron transport, one of the most fundamental reactions in nature. Understanding the link between the structure and electron transport properties of proteins is of utmost importance when using them as templates for synthetic systems. In close collaboration with single-molecule experiments, Resource researchers performed simulations using NAMD to understand the role of secondary structure in electron transport. The results, published in a recent paper in PNAS, highlight the importance of helical conformations in electron transport of peptides and provide broad avenues for understanding the electronic properties of proteins.
