Beyond Methane Oxidation: The Protein Landscape of ANME‐2a Reveals an Integrated System for Diazotrophy and Membrane Fortification

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
A protein interaction network of ANME‐2a uncovers a modular blueprint where core methane oxidation is energetically coupled to nitrogen fixation and membrane lipid biosynthesis. This integrated system explains the archaeon's metabolic autonomy and resilience in its extreme deep‐sea niche.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Transposon and deletion mutagenesis of genes involved in perchlorate reduction in Azospira suillum PS. [PDF]

, 2013
UnlabelledAlthough much work on the biochemistry of the key enzymes of bacterial perchlorate reduction, chlorite dismutase, and perchlorate reductase has been published, understanding of the molecular mechanisms of this metabolism has been somewhat ...

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 ...

Genome-centric metagenomics reveals electroactive syntrophs in a conductive particle-dependent consortium from coastal sediments

Nature Communications
Conductive 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 ...

Diverse Microorganisms in Sediment and Groundwater Are Implicated in Extracellular Redox Processes Based on Genomic Analysis of Bioanode Communities

Frontiers in Microbiology, 2020
Extracellular electron transfer (EET) between microbes and iron minerals, and syntrophically between species, is a widespread process affecting biogeochemical cycles and microbial ecology.

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.
