Role of multiheme cytochromes involved in extracellular anaerobic respiration in bacteria [PDF]

Protein Science, 2020
AbstractHeme containing proteins are involved in a broad range of cellular functions, from oxygen sensing and transport to catalyzing oxidoreductive reactions. The two major types of cytochrome (b‐type and c‐type) only differ in their mechanism of heme attachment, but this has major implications for their cellular roles in both localization and ...

Cell surface differences within the genus Methanosarcina shape interactions with the extracellular environment [PDF]

Journal of Bacteriology
Methanosarcina are metabolically versatile methanogenic archaea that can perform extracellular electron transfer (EET), with important ecological and biotechnological implications.

Deciphering the Mto electron uptake pathway of Sideroxydans lithotrophicus ES-1 [PDF]

Applied and Environmental Microbiology
The freshwater, chemolithoautotrophic, Gram-negative bacterium Sideroxydans lithotrophicus ES-1 (ES-1) is thought to couple extracellular electron transfer (EET) to energy conservation through the Mto pathway and additional porin-cytochrome complexes ...

Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications. [PDF]

Environ Microbiol Rep
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions

Crucial roles of intracellular cyclic di-GMP in impacting the genes important for extracellular electron transfer by Geobacter metallireducens [PDF]

Applied and Environmental Microbiology
To investigate the roles of intracellular c-di-GMP in bacterial extracellular electron transfer (EET), three Geobacter metallireducens strains with high (Gme-H), intermediate (Gme-C), and low (Gme-L) intracellular levels of c-di-GMP were constructed via ...

Iron or sulfur respiration—an adaptive choice determining the fitness of a natronophilic bacterium Dethiobacter alkaliphilus in geochemically contrasting environments

Frontiers in Microbiology, 2023
Haloalkaliphilic microorganisms are double extremophiles functioning optimally at high salinity and pH. Their typical habitats are soda lakes, geologically ancient yet widespread ecosystems supposed to harbor relict microbial communities.

Tunneling-to-Hopping Transition in Multiheme Cytochrome Bioelectronic Junctions

The Journal of Physical Chemistry Letters, 2023
Multiheme cytochromes (MHCs) have attracted much interest for use in nanobioelectronic junctions due to their high electronic conductances. Recent measurements on dry MHC junctions suggested that a coherent tunneling mechanism is operative over surprisingly long long distances (>3 nm), which challenges our understanding of coherent transport phenomena.

50 Years of Giese Reaction - a Personal View. [PDF]

Angew Chem Int Ed Engl
The Giese‐Reaction celebrates its 50. Birthday, it is a cyclic radical chain reaction centered around C,C‐bond formation in a three component synthesis. This minireview speaks about the birth of the name‐reaction, explains how the complete understanding of its reaction mechanism stimulates new methods in organic synthesis, and why it can proceed in ...

Deciphering Molecular Factors That Affect Electron Transfer at the Cell Surface of Electroactive Bacteria: The Case of OmcA from Shewanella oneidensis MR-1

Microorganisms, 2022
Multiheme cytochromes play a central role in extracellular electron transfer, a process that allows microorganisms to sustain their metabolism with external electron acceptors or donors.
