Electron transfer in multicentre redox proteins: from fundamentals to extracellular electron transfer. [PDF]

Biosci Rep
Multicentre redox proteins participate in diverse metabolic processes, such as redox shuttling, multielectron catalysis, or long-distance electron conduction. The detail in which these processes can be analysed depends on the capacity of experimental methods to discriminate the multiple microstates that can be populated while the protein changes from ...

Physiological Benefits of Oxygen-Terminating Extracellular Electron Transfer. [PDF]

mBio, 2022
Extracellular electron transfer (EET) is a process via which certain microorganisms, such as bacteria, exchange electrons with extracellular materials by creating an electrical link across their membranes. EET has been studied for the reactions on solid materials such as minerals and electrodes with implication in geobiology and biotechnology.

Mechanisms of extracellular electron transfer in anaerobic methanotrophic archaea. [PDF]

Nat Commun, 2023
AbstractAnaerobic methanotrophic (ANME) archaea are environmentally important uncultivated microorganisms mitigating the release of the potent greenhouse gas methane. During methane oxidation ANME archaea engage in extracellular electron transfer (EET) with other microorganisms, metal oxides, and electrodes, through a currently unknown mechanism.

Cytochromes in Extracellular Electron Transfer in Geobacter. [PDF]

Appl Environ Microbiol, 2021
Extracellular electron transfer (EET) is an important biological process in microbial physiology as found in dissimilatory metal oxidation/reduction and interspecies electron transfer in syntrophy in natural environments. EET also plays a critical role in microorganisms relevant to environmental biotechnology in metal-contaminated areas ...

Shewanella secretes flavins that mediate extracellular electron transfer [PDF]

Proceedings of the National Academy of Sciences, 2008
Bacteria able to transfer electrons to metals are key agents in biogeochemical metal cycling, subsurface bioremediation, and corrosion processes. More recently, these bacteria have gained attention as the transfer of electrons from the cell surface to ...

Conjugative plasmids inhibit extracellular electron transfer in Geobacter sulfurreducens. [PDF]

Front Microbiol, 2023
Geobacter sulfurreducens is part of a specialized group of microbes with the unique ability to exchange electrons with insoluble materials, such as iron oxides and electrodes. Therefore, G. sulfurreducens plays an essential role in the biogeochemical iron cycle and microbial electrochemical systems. In G.

Cysteine-Mediated Extracellular Electron Transfer of Lysinibacillus varians GY32. [PDF]

Microbiol Spectr, 2022
Extracellular electron transport (EET) is a key driving force in biogeochemical element cycles and microbial chemical-electrical-optical energy conversion on the Earth. Gram-positive bacteria are ubiquitous and even dominant in EET-enriched environments.

Transcriptional regulation of living materials via extracellular electron transfer. [PDF]

Nat Chem Biol
Engineered living materials combine the advantages of biological and synthetic systems by leveraging genetic and metabolic programming to control material-wide properties. Here, we demonstrate that extracellular electron transfer (EET), a microbial respiration process, can serve as a tunable bridge between live cell metabolism and synthetic material ...

Putative Extracellular Electron Transfer in Methanogenic Archaea [PDF]

Frontiers in Microbiology, 2021
It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species. Methanothrix harundinacea and Methanosarcina horonobensis retrieve electrons from Geobacter metallireducens via direct interspecies ...
