Is the direct observation of electronic coherence in electron transfer reactions possible? [PDF]
The Journal of Chemical Physics, 1997 The observability of electronic coherence in electron transfer reactions is discussed. We show that under appropriate circumstances large-amplitude oscillations can be found in the electronic occupation probabilities.

Studying direct electron transfer by site-directed immobilization of cellobiose dehydrogenase. [PDF]
ChemElectroChem, 2019 AbstractCovalent coupling between a surface‐exposed cysteine residue and maleimide groups was used to immobilize variants of Myriococcum thermophilum cellobiose dehydrogenase (MtCDH) at multiwall carbon nanotube electrodes. By introducing individual cysteine residues at particular places on the surface of the flavodehydrogenase domain of the ...

Putative Extracellular Electron Transfer in Methanogenic Archaea
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.

Molecular Basis for Directional Electron Transfer [PDF]
Journal of Biological Chemistry, 2010 Biological macromolecules involved in electron transfer reactions display chains of closely packed redox cofactors when long distances must be bridged. This is a consequence of the need to maintain a rate of transfer compatible with metabolic activity in the framework of the exponential decay of electron tunneling with distance.

Directed evolution of P450cin for mediated electron transfer [PDF]
Protein Engineering Design and Selection, 2016 Directed evolution is a powerful method to optimize enzyme properties for application demands. Interesting targets are P450 monooxygenases which catalyze the stereo- and regiospecific hydroxylation of chemically inert C-H bonds. Synthesis employing P450s under cell-free reaction conditions is limited by low total turnover numbers, enzyme instability ...

Direct arylation reaction of heteroarenes mediated by photoinduced electron transfer
Journal of Photochemistry and Photobiology, 2023 Electron donor–acceptor (EDA) complexes are interesting chemical species that function as molecular complexes. In this context, chemists have actively studies the use of halogen bonding as a noncovalent interaction in photochemistry.

Methanobacterium Capable of Direct Interspecies Electron Transfer [PDF]
Environmental Science & Technology, 2020 Direct interspecies electron transfer (DIET) from bacteria to methanogens is a revolutionary concept for syntrophic metabolism in methanogenic soils/sediments and anaerobic digestion. Previous studies have indicated that the potential for DIET is limited to methanogens in the Methanosarcinales, leading to the assumption that an abundance of other types

Direct heterogeneous electron transfer of theophylline oxidase [PDF]
Biosensors and Bioelectronics, 2004 Direct electron transfer (DET) was shown between the heme containing enzyme theophylline oxidase (ThO) and the surface of both graphite and gold electrodes. As proof on graphite a steady state current for theophylline was recorded using the electrode modified with adsorbed ThO.

Mechanisms of electron transfer to insoluble terminal acceptors in chemoorganotrophic bacteria [PDF]
The Ukrainian Biochemical Journal, 2014 The mechanisms of electron transfer of association of chemoorganotrophic bacteria to the anode in microbial fuel cells are summarized in the survey. These mechanisms are not mutually exclusive and are divided into the mechanisms of mediator electron ...

Direct Interspecies Electron Transfer Mediated by Graphene Oxide-Based Materials
Frontiers in Microbiology, 2020 Conductive materials are known to promote direct interspecies electron transfer (DIET) by electrically bridging microbial cells. Previous studies have suggested that supplementation of graphene oxide (GO) based materials, including GO, and reduced GO ...
