Current Opinion in Chemical Biology, 1998
The tunneling pathway framework description of protein electron transfer reactions has prompted a lively discussion of how structure and evolution influence electron transfer rates. Recent protein and model system experiments, performed in solution and in organized media, are providing answers.

Oxidoreductases are a special class of enzymes that use the redox mechanism for the efficient transformation of organic substrates. Most oxidoreductases contain metals in the active site and, for optimal functioning, require the participation of a small co-substrate with the ability to donate electrons.

Proton-Assisted Electron Transfer
The Journal of Physical Chemistry A, 1998The case for highly selective long range “proton assisted” electron transfer in biomolecules (PA-ET), involving the hopping of protons and hydrogen atoms along H-bond chains connecting two redox sites, is discussed and analyzed on systems closely resembling typical biochemical sequences. These systems consist of an electron acceptor, an H-bond/covalent-

Many oxidoreductases are constructed from (a) local sites of strongly coupled substrate-redox cofactor partners participating in exchange of electron pairs, (b) electron pair/single electron transducing redox centers, and (c) nonadiabatic, long-distance, single-electron tunneling between weakly coupled redox centers.

Extracellular electron transfer
Cellular and Molecular Life Sciences, 2001Results from several laboratories indicate that extracellular electron transfer may be a general mechanism whereby microoorganisms generate energy for cell growth and/or maintenance. Specifically, bacteria can use redox-active organic small molecules, generated outside or inside the cells, to shuttle electrons between reduced and oxidized compounds ...

Photochemically Induced Electron Transfer
Methods, 2001Biochemical reactions involving electron transfer between substrates or enzyme cofactors are both common and physiologically important; they have been studied by means of a variety of techniques. In this paper we review the application of photochemical methods to the study of intramolecular electron transfer in hemoproteins, thus selecting a small ...

Electron-Induced Proton Transfer
The Journal of Physical Chemistry B, 2021The pathway of activationless proton transfer induced by an electron-transfer reaction is studied theoretically. Long-range electron transfer produces highly nonequilibrium medium polarization that can drive proton transfer through an activationless transition during the process of thermalization, dynamically altering the screening of the electron ...

Electron transfer processes are at the core of all oxidation–reduction reactions, including those associated with electrochemistry and corrosion. Photoelectrochemistry and solar energy conversion, organic light emitting diodes, and molecular electronic devices, all dominated by electron transfer and electron transmission in molecular systems, are ...
