Effective two-state systems in bridge-mediated electron transfer. A Green function analysis
Skourtis, Spiros S.; Onuchic, J. N. (1993)We derived the criteria for the validity of the effective two-state picture of bridge-mediated electron transfer for a one-electron many state system. The leading error associated with the two-state reduction is calculated. ...

Electron transfer in proteins: A novel approach for the description of donor-acceptor coupling
Skourtis, Spiros S.; Regan, J. J.; Onuchic, J. N. (1994)We propose a nonperturbative Green's function approach for analyzing the effects of conformation on electron-transfer matrix elements in proteins. This approach allows the analysis (at all levels of detail) of the contributions ...

A method to analyze multi-pathway effects on protein mediated donor-acceptor coupling interactions
Skourtis, Spiros S.; Onuchic, J. N.; Beratan, David N. (1996)Current strategies for analyzing donor-acceptor interactions involve mapping the dominant coupling pathways or families of pathways, followed by a numerical estimate of the interaction mediated by the paths. This strategy ...

A new look at the primary charge separation in bacterial photosynthesis
Skourtis, Spiros S.; Da Silva, A. J. R.; Bialek, W.; Onuchic, J. N. (1992)A theory for the primary charge separation in photosynthetic bacteria is presented. We propose that this reaction may lie in a regime that is different from the traditional nonadiabatic (golden rule) regime. In the context ...

Pathways, pathway tubes, pathway docking, and propagators in electron transfer proteins
Curry, W. B.; Grabe, M. D.; Kurnikov, I. V.; Skourtis, Spiros S.; Beratan, David N.; Regan, J. J.; Aquino, A. J. A.; Beroza, P.; Onuchic, J. N. (1995)The simplest views of long-range electron transfer utilize flat one-dimensional barrier tunneling models, neglecting structural details of the protein medium. The pathway model of protein electron transfer reintroduces ...

The two-state reduction for electron and hole transfer in bridge-mediated electron-transfer reactions
Skourtis, Spiros S.; Beratan, David N.; Onuchic, J. N. (1993)We present a unified analysis of the two-state reduction in bridge-mediated electron transfer for both electron and hole transfer. The parameter that characterizes the leading error associated with a two-state reduction ...
