A Simple, Rapid, and Highly Efficient Gene Expression System for Multiheme Cytochromes c [PDF]

Bioscience, Biotechnology, and Biochemistry, 2001
The genes of tetraheme cytochrome c3 and hexadecaheme high-molecular-weight cytochrome c from Desulfovibrio vulgaris could be overexpressed as holoproteins in Shewanella oneidensis TSP-C using pUC-type vectors of E. coli. Surprisingly, S. oneidensis was transformed directly by pUC-type vectors through electroporation.

Photoreduction of Shewanella oneidensis Extracellular Cytochromes by Organic Chromophores and Dye-Sensitized TiO2. [PDF]

, 2016
The transfer of photoenergized electrons from extracellular photosensitizers across a bacterial cell envelope to drive intracellular chemical transformations represents an attractive way to harness nature's catalytic machinery for solar-assisted chemical

Deep-branching ANME-1c archaea grow at the upper temperature limit of anaerobic oxidation of methane

Frontiers in Microbiology, 2022
In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the methane formed in anoxic layers, preventing this greenhouse gas from reaching the water column and finally the atmosphere.

Extracellular electron uptake in Methanosarcinales is independent of multiheme c -type cytochromes [PDF]

Scientific Reports, 2019
Abstract The co-occurrence of Geobacter and Methanosarcinales is often used as a proxy for the manifestation of direct interspecies electron transfer (DIET) in man-made and natural aquatic environments. We previously reported that not all

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1027-1034, May 2026.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...

A suite of de novo c-type cytochromes for functional oxidoreductase engineering [PDF]

, 2016
Central to the design of an efficient de novo enzyme is a robust yet mutable protein scaffold. The maquette approach to protein design offers precisely this, employing simple four-α-helix bundle scaffolds devoid of evolutionary complexity and with proven

Reconstruction of Extracellular Respiratory Pathways for Iron(III) Reduction in Shewanella Oneidensis Strain MR-1 [PDF]

, 2012
Shewanella oneidensis strain MR-1 is a facultative anaerobic bacterium capable of respiring a multitude of electron acceptors, many of which require the Mtr respiratory pathway.

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Rational Design of Covalent Multiheme Cytochrome‐Carbon Dot Biohybrids for Photoinduced Electron Transfer

Advanced Functional Materials, 2023
AbstractBiohybrid systems can combine inorganic light‐harvesting materials and whole‐cell biocatalysts to utilize solar energy for the production of chemicals and fuels. Whole‐cell biocatalysts have an intrinsic self‐repair ability and are able to produce a wide variety of multicarbon chemicals in a sustainable way with metabolic engineering.

Structure of Geobacter OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times

eLife, 2022
While early genetic and low-resolution structural observations suggested that extracellular conductive filaments on metal-reducing organisms such as Geobacter were composed of type IV pili, it has now been established that bacterial c-type cytochromes ...
