Assessment of the manganese cluster’s oxidation state via photoactivation of photosystem II microcrystals [Biophysics and Computational Biology]

Knowledge of the manganese oxidation states of the oxygen-evolving Mn4CaO5 cluster in photosystem II (PSII) is crucial toward understanding the mechanism of biological water oxidation. There is a 4 decade long debate on this topic that historically originates from the observation of a multiline electron paramagnetic resonance (EPR) signal with...
