Methane-Dependent Extracellular Electron Transfer at the Bioanode by the Anaerobic Archaeal Methanotroph “Candidatus Methanoperedens”

Frontiers in Microbiology, 2022
Anaerobic methanotrophic (ANME) archaea have recently been reported to be capable of using insoluble extracellular electron acceptors via extracellular electron transfer (EET).

Defined Electrosynthetic Microbial Consortia Reveal Electron Transfer Modes Governing Acetate Production

Advanced Science, Volume 13, Issue 6, 30 January 2026.
Spatially resolved Shewanella–acetogen interactions link DIET and MET pathways to acetate formation, offering a generalizable framework for designing structured, high‐efficiency microbial electrosynthesis systems. Abstract Precise manipulation of interspecies electron transfer (IET) is critical for advancing microbial electrosynthesis (MES) toward ...

Diversity and Metabolic Potential of the Terrestrial Mud Volcano Microbial Community with a High Abundance of Archaea Mediating the Anaerobic Oxidation of Methane

Life, 2021
Terrestrial mud volcanoes (TMVs) are important natural sources of methane emission. The microorganisms inhabiting these environments remain largely unknown. We studied the phylogenetic composition and metabolic potential of the prokaryotic communities of

Assignment of Individual Metal Redox States in a Metalloprotein by Crystallographic Refinement at Multiple X-ray Wavelengths [PDF]

, 2007
A method is presented to derive anomalous scattering contributions for individual atoms within a protein crystal by collecting several sets of diffraction data at energies spread along an X-ray absorption edge of the element in question.

Composition and Metabolic Potential of Fe(III)-Reducing Enrichment Cultures of Methanotrophic ANME-2a Archaea and Associated Bacteria

Microorganisms, 2023
The key microbial group involved in anaerobic methane oxidation is anaerobic methanotrophic archaea (ANME). From a terrestrial mud volcano, we enriched a microbial community containing ANME-2a, using methane as an electron donor, Fe(III) oxide ...

The genome of Pelobacter carbinolicus reveals surprising metabolic capabilities and physiological features [PDF]

, 2012
Background The bacterium Pelobacter carbinolicus is able to grow by fermentation, syntrophic hydrogen/formate transfer, or electron transfer to sulfur from short-chain alcohols, hydrogen or formate; it does not oxidize acetate and is not known to ferment

Extracellular catalysis of environmental substrates by Shewanella oneidensis MR‐1 occurs via active sites on the C‐terminal domains of MtrC

Protein Science, Volume 34, Issue 8, August 2025.
Abstract The Gram‐negative Shewanellaceae family is well known for its ability to transfer catabolically derived electrons to extracellular terminal electron acceptors through electron conduits that permeate the outer membrane. The primary conduit is MtrCAB, a trimeric porin‐cytochrome complex that contains the cell surface exposed decaheme cytochrome ...

EPR determination of interaction redox potentials in a multiheme cytochrome: cytochrome c3 from Desulfovibrio desulfuricans Norway [PDF]

European Journal of Biochemistry, 1988
In cytochromes c3 which contain four hemes per molecule, the redox properties of each heme may depend upon the redox state of the others. This effect can be described in terms of interaction redox potentials between the hemes and must be taken into account in the characterization of the redox properties of the molecule.

Constructing a man-made c-type cytochrome maquette in vivo:electron transfer, oxygen transport and conversion to a photoactive light harvesting maquette [PDF]

, 2014
The successful use of man-made proteins to advance synthetic biology requires both the fabrication of functional artificial proteins in a living environment, and the ability of these proteins to interact productively with other proteins and substrates in
