Direct Electron Transfer of Enzymes Facilitated by Cytochromes. [PDF]
ChemElectroChem, 2019 AbstractThe direct electron transfer (DET) of enzymes has been utilized to develop biosensors and enzymatic biofuel cells on micro‐ and nanostructured electrodes. Whereas some enzymes exhibit direct electron transfer between their active‐site cofactor and an electrode, other oxidoreductases depend on acquired cytochrome domains or cytochrome subunits ...

The Role of Exopolysaccharides in Direct Interspecies Electron Transfer
Frontiers in Microbiology, 2022 Direct interspecies electron transfer (DIET) is an effective mechanism for microbial species to exchange electrons cooperatively during syntrophic metabolism. It is generally accepted that DIET is mainly mediated by electrically conductive pili and outer

Recent Advances in the Direct Electron Transfer-Enabled Enzymatic Fuel Cells [PDF]
Frontiers in Chemistry, 2021 Direct electron transfer (DET), which requires no mediator to shuttle electrons from enzyme active site to the electrode surface, minimizes complexity caused by the mediator and can further enable miniaturization for biocompatible and implantable devices.

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.
