The corresponding lifetime 1/kET was estimated from the rate expressions, Eqs. (1) and (2), based on the computed redox potentials Em(A1) and Em(FX).
Calculated by adding the calculated shift of the Em(FX) between the native PSI complex and P700-FX core (42 mV) to the measured Em(FX) in the native PSI complex.
lifetime calculated with reorganization energy λ = 1.0.
Based on the measured Em(FX) = −670 mV in the native PSI complex (3).
Estimated by Eq. 2.
Estimated by Eq. 1.
