Oxidation-Reduction
Research News and Information
Definition of 'Oxidation-Reduction'A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Common names: Oxidation-Reduction; Oxidation Reduction; Redox |

The redox potential of the primary plastoquinone electron acceptor Q(A), E(m)(Q(A)/Q(A)(-)), in an oxygen-evolving photosystem (PS) II complex from a thermophilic cyanobacterium Thermosynechococcus elongatus was determined to be -140 +/- 2 mV vs. ... Read more...
Interdomain contacts in flavocytochrome b(2), a mutational analysis.
15 Nov 2009 Each flavocytochrome b(2) (l-lactate cytochrome c oxidoreductase) subunit consists of an N-terminal cytochrome domain and a C-terminal flavodehydrogenase (FDH) domain. In the enzyme crystal structure, only two heme domains are visible per enzyme ... Read more...
Substrate redox potential controls superoxide production kinetics in the cytochrome bc complex.
15 Nov 2009 The Q-cycle mechanism of the cytochrome bc(1) complex maximizes energy conversion during the transport of electrons from ubiquinol to cytochrome c (or alternate physiological acceptors), yet important steps in the Q-cycle are still hotly debated, ... Read more...
