In spinach photosystem II (PSII) membranes, the tetranuclear manganese cluster of the oxygen-evolving complex (OEC) can be reduced by incubation with nitric oxide at -30 degrees C to a state which is characterized by an Mn(2)(II, III) EPR multiline signal [Sarrou, J., Ioannidis, N., Deligiannakis, Y., and Petrouleas, V. (1998) Biochemistry 37, 3581-3587]. This state was recently assigned to the S(-)(2) state of the OEC [Schansker, G., Goussias, C., Petrouleas, V., and Rutherford, A. W. (2002… CONTINUE READING
