Fig. 3.

Tyr_Z and Tyr_D oxidation kinetics at 3465 G in the reduced Mn-depleted PS II membranes, induced by a train of five 532 nm (black traces) or 732 nm laser flashes (red traces) at pH 4.7 (A), pH 6.3 (B) and pH 8.5 (C). Each trace represents an average of four single measurements in independent samples. Tyr_Z oxidation kinetics induced by single 532 nm (black traces) or 732 nm laser flash (red traces) at: pH 4.7 (D), pH 6.3 (E) and pH 8.5 (F). Each trace represents an average of 199 flashes. EPR conditions are the same as in Fig. 2
