Biological electron-transfer reactions.
A wide range of biological processes makes extensive use of electron-transfer reactions. Rigorous characterization of a biological electron-transfer reaction requires a combination of kinetic, thermodynamic, structural and theoretical methods. The rate of electron transfer from an electron donor to an electron acceptor through a protein is dependent on the difference in reduction potential of t...
متن کاملA Model for Orientation Effects in Electron‐Transfer Reactions
A method for solving the single-particle Schrooinger equation with an oblate spheroidal potential of finite depth is presented. The wave functions are then used to calculate the matrix element T. h"h ~ w 1c appears in theories of nonadiabatic electron transfer. The results illustrate the effects of mutual orientation and separation of the two centers on T BA. Trends in these results are discuss...
متن کاملPersistence of structure over fluctuations in biological electron-transfer reactions.
In the soft-wet environment of biomolecular electron transfer, it is possible that structural fluctuations could wash out medium-specific electronic effects on electron tunneling rates. We show that beyond a transition distance (2-3 A in water and 6-7 A in proteins), fluctuation contributions to the mean-squared donor-to-acceptor tunneling matrix element are likely to dominate over the average ...
متن کاملOn the theory of electron transfer reactions at semiconductorÕliquid interfaces. II. A free electron model
Electron transfer reactions at semiconductor/liquid interfaces are studied using the Fermi Golden rule and a free electron model for the semiconductor and the redox molecule. Bardeen’s method is adapted to calculate the coupling matrix element between the molecular and semiconductor electronic states where the effective electron mass in the semiconductor need not equal the actual electron mass....
متن کاملDirectionality of electron-transfer reactions in photosystem I of prokaryotes: universality of the bidirectional electron-transfer model.
The electron-transfer (ET) reactions in photosystem I (PS I) of prokaryotes have been investigated in wild-type cells of the cyanobacterium Synechocystis sp. PCC 6803, and in two site-directed mutants in which the methionine residue of the reaction center subunits PsaA and PsaB, which acts as the axial ligand to the primary electron chlorophyll acceptor A(0), was substituted with histidine. Ana...
