The relationship between energy-dependent exciton quenching and the pmf generated solely by LEF. Estimates of energy-dependent quenching (qE) and the pmf generated solely by LEF (i.e., pmfLEF) were obtained as in Figs. 1 and 2, respectively. ATP synthase content in Wt (A) and pgr5 (B) was estimated by Western blot analyses by using polyclonal serum directed against the β-subunit of the ATP synthase (Inset). Conditions and symbols are as in Fig. 1. Error bars represent SE for n = 3–6.
