Electron transfer in biology

Molecular Physics, 1989
Table VII presents a list of the topics I have discussed. Underlying biological electron transfer which employs metal ions overwhelmingly is the intimacy of the interaction between metal ion properties and protein properties. Attacking the problems is attacking a cornerstone of life - bioenergetics. It is appropriate that this is the Heyrovsky Memorial

Electron Transfer

2023
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.

Studies on the electron transfer system IV. The electron transfer particle

Biochimica et Biophysica Acta, 1956
The preparation and properties of an electron transfer particle (ETP) obtained from beef heart mitochondria are described. ETP catalyzes the oxidation of 5.7 μmoles DPNH and 2 μmoles succinate per min per mg at 38°. This specific activity is 3 to 5 times greater than that of the original mitochondrial suspension.

Electron transfer mechanisms in electron transfer chains

Journal of Biological Physics, 1973
Mechanisms responsible for the transfer of electrons through mitochondrial and photosynthetic electron transport chains are considered. Mechanisms considered include diffusion, ligand-mediated transfer, tunneling and semiconduction. Perturbations which create satisfactory conditions for electron transfer are also considered. There is a brief discussion

Electron transfer in quinoproteins

Archives of Biochemistry and Biophysics, 2004
Soluble quinoprotein dehydrogenases oxidize a wide range of sugar, alcohol, amine, and aldehyde substrates. The physiological electron acceptors for these enzymes are not pyridine nucleotides but are other soluble redox proteins. This makes these enzymes and their electron acceptors excellent systems with which to study mechanisms of long-range ...

Proton-Assisted Electron Transfer

The Journal of Physical Chemistry A, 1998
The 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-

Electron transfer in DNA

Current Opinion in Chemical Biology, 2002
Electrons migrate over long distances along the DNA in a multistep hopping process where the rate of each step depends strongly upon its length. The efficiency of this process is not only determined by the electron transfer rates but also by competing reactions with water, in which the charge carriers are trapped.

Photochemically Induced Electron Transfer

Methods, 2001
Biochemical 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 ...
