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.

Syntrophy Goes Electric: Direct Interspecies Electron Transfer.
Annual Review of Microbiology, 2017 Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for DIET have primarily been studied in defined cocultures in which Geobacter species are one of the DIET partners. Electrically conductive pili (e-pili) can be

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.

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.

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 ...

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 ...

Role of direct microbial electron transfer in corrosion of steels [PDF]
, 2009 It has recently been discovered that many microbial species have the capacity to connect their metabolism to solid electrodes, directly exchanging electrons with them through membrane-bound redox compounds,nevertheless such a direct electron transfer ...

Aza-heterocyclic Receptors for Direct Electron Transfer Hemoglobin Biosensor. [PDF]
Sci Rep, 2017 AbstractDirect Electron Transfer biosensors, facilitating direct communication between the biomolecule of interest and electrode surface, are preferable compared to enzymatic and mediator based sensors. Although hemoglobin (Hb) contains four redox active iron centres, direct detection is not possible due to inaccessibility of iron centres and formation
