Many subsurface microorganisms couple their metabolism to the reduction or oxidation of
extracellular substrates. For example, anaerobic mineral-respiring bacteria can use external …

Using a series of multiheme cytochromes, the metal-reducing bacterium Shewanella
oneidensis MR-1 can perform extracellular electron transfer (EET) to respire redox-active …

Extracellular electron transfer is the key metabolic trait that enables some bacteria to play a
significant role in the biogeochemical cycling of metals and in bioelectrochemical devices …

Dissimilatory metal reducing organisms play key roles in the biogeochemical cycle of metals
as well as in the durability of submerged and buried metallic structures. The molecular …

The metal-reducing bacterium Shewanella oneidensis MR-1 produces extensions of its
outer membrane (OM) and periplasm that contain cytochromes responsible for extracellular …

Microorganisms overcome the considerable hurdle of respiring extracellular solid substrates
by deploying large multiheme cytochrome complexes that form 20 nanometer conduits to …

The biochemical mechanisms by which microbes interact with extracellular soluble metal
ions and insoluble redox-active minerals have been the focus of intense research over the …

The mineral-respiring bacterium Shewanella oneidensis uses a protein complex, MtrCAB,
composed of two decaheme cytochromes, MtrC and MtrA, brought together inside a …

Many species of bacteria can generate energy in the anoxic subsurface by directly coupling
intracellular oxidative reactions to the reduction of extracellular metal oxides. Coupling these …

The multiheme cytochrome MtrA enables microbial respiration by transferring electrons
across the outer membrane to extracellular electron acceptors. While structural studies have …
