A microscopic method for simulating quantum mechanical, nuclear tunneling effects in
biological electron transfer reactions is presented and applied to several electron transfer …

The initial electron transfer dynamics during photosynthesis have been studied in
Rhodobacter sphaeroides reaction centers from wild type and 14 mutants in which the …

A description is given of a method to calculate the electron transfer reorganization energy (λ)
in proteins using the linear or nonlinear Poisson-Boltzmann (PB) equation. Finite difference …

The spin—boson model is applied to describe the coupling between protein motion and
electron transfer for the primary electron transfer in the photosynthetic reaction center of …

A general method is demonstrated for experimentally obtaining the rate constant of electron
transfer as a function of the free energy of the reaction in nonoriented systems. An external …

We investigate how electron transfer is controlled by protein motion in photosynthetic
reaction centers. Our study is based on molecular dynamics (MD) simulations of two electron …

The rate of the electron-transfer reaction between bacteriopheophytin and the first quinone
in isolated reaction centers of Rhodopseudomonas sphaeroides has an unusual …

Revised Manuscript Received December 4, 1987 abstract: The mechanism of the initial
electron-transfer process in thereaction centers of photosynthetic bacteria is examined by …

Studies of electron-transfer reactions, which have progressed rapidly on both the ex:
perimental and theoretical fronts, have been the subject of several reviews (1-5). Although …

The fluorescence intensity from randomly oriented, immobilized R b. sphaeroides reaction
centers at 77 K increases in the presence of an externally applied electric field. We have …
