What is Protein Electron Transfer: a Numerical Study of Tunneling Through Fluctuating Bridges about?

A central challenge of protein electron-transfer theory is to understand how the protein dynamics influences the electron Ž . tunneling from donor to acceptor. It is shown that tunneling as a function of time through a fluctuating protein bridge is drastically different from tunneling through a chemically identical static bridge. The static two-state approximation that leads to the donor-acceptor matrix element T , is therefore inadequate. A time-dependent two-state approximation is found that DA describes the tunneling dynamics through a fluctuating bridge. The fluctuating system electronic Hamiltonians are constructed from molecular dynamics trajectories at the CNDO-SCF level.
