Table II. Fit parameters describing the decay of “out-of-phase” ESE.

Fit parameters are shown describing the decay of the ESE after the actinic laser flash in thylakoids isolated from the wild type and FN68 strain. Ascorbate (10 mm) with 200 µm phenazinemethosulfate as mediator was used to reduce P₇₀₀⁺ in the experiments performed at 265 K. The other samples were dark adapted for 30 min in the presence of Na₂S₂O₄ (11 mm, pH 8; F_A/B reduced, F_X oxidized). Preillumination of the sample for 5 min at 205 K results in full reduction of F_A/B and more than 80% reduction of F_X (F_A/B/X reduced). The decays were fitted to a sum of an exponential function, y(t) = α₁e^−t/τ1 + α₂e^−t/τ2 and τ_av = α₁ × τ₁ + α₂ × τ₂, with α₁ + α₂ = 1 (where α is the associated amplitude).
