Abstract excerpt
The active site of water oxidation in Photosystem II (PSII) is a Mn4CaO5 cluster that is located in a cavity between the D1 and CP43 protein subunits by which it is coordinated. The remainder of this cavity is filled with water molecules, which serve as a source of substrate and participate in poorly understood hydrogen bond networks that may modulate the function of the Mn4CaO5 cluster. These water molecules...
