Abstract

Abstract. Steady progress in unveiling nature’s long-range charge transport mechanisms in redox proteins, and in the development of versatile self-assembling scaffolds and de novo proteins by design are separate fields that soon may intersect to yield the first artificial bioelectronic wires. Here we summarize compelling developments in these areas that put a spotlight on the prospect of their convergence, featuring in particular recent work by Dai et al. that clearly illustrates success in intentional design with nuanced control, binding multiple c-type hemes into a specific ordered array bearing the essential hallmarks of heme chains in bacterial multiheme cytochromes.
