In this contribution, the authors provide a more complete interpretation of earlier EPR data and include new experimental data on the magnetic properties of the g = 4.1 S/sub 2/ state EPR signal and the S/sub 2/ state multiline EPR signal produced by 245 K illumination in active state samples. An interpretation of the temperature-dependence data of the S/sub 2/ state EPR signal from NH/sub 4/Cl-treated PSII membranes was presented. These data can be best explained by a model of the S/sub 2/ state which consists of a mixed-valence manganese tetramer.
