Photosensitised Multiheme Cytochromes as Light‐Driven Molecular Wires and Resistors [PDF]
ChemBioChem, 2018 Multiheme cytochromes possess closely packed redox‐active hemes arranged as chains spanning the tertiary structure. Here we describe five variants of a representative multiheme cytochrome engineered as biohybrid phototransducers for converting light into

Comparative structure-potentio-spectroscopy of the Shewanella outer membrane multiheme cytochromes [PDF]
Current Opinion in Electrochemistry, 2017 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 processes requires electron transfer networks that extend from the

Delineating redox cooperativity in water-soluble and membrane multiheme cytochromes through protein design. [PDF]
Protein SciAbstract Nature has evolved diverse electron transport proteins and multiprotein assemblies essential to the generation and transduction of biological energy. However, substantially modifying or adapting these proteins for user‐defined applications or to gain fundamental mechanistic insight can be hindered by their inherent complexity.

Genome-centric metagenomics reveals electroactive syntrophs in a conductive particle-dependent consortium from coastal sediments [PDF]
Nature CommunicationsConductive particles are common in coastal sediments, yet their role in shaping methane-producing communities and pathways remains unclear. We applied genome-resolved metagenomics to a sediment-derived consortium serially transferred for a decade and ...

MmcA is an electron conduit that facilitates both intracellular and extracellular electron transport in Methanosarcina acetivorans [PDF]
Nature CommunicationsMethanogens are a diverse group of Archaea that obligately couple energy conservation to the production of methane. Some methanogens encode alternate pathways for energy conservation, like anaerobic respiration, but the biochemical details of this ...
