Effect of pH on the H/D-isotope effect and on the Arrhenius activation energy of the charge transfer through F0. (A) H/D isotope effect was calculated as the ratio of the rate constants in H2O and D2O (data taken from Fig. 3). (B) The pH-dependence of the Arrhenius activation energy (Ea). Measurements were done in the presence of 3 μM myxothiazol in the temperature interval from 3°C to 40°C. A single experiment was done at pH 9; other points are the average of at least three experiments.
