Energetics of proton release on the first oxidation step in the water-oxidizing enzyme

In photosystem II (PSII), the Mn(4)CaO(5) cluster catalyses the water splitting reaction. The crystal structure of PSII shows the presence of a hydrogen-bonded water molecule directly linked to O4. Here we show the detailed properties of the H-bonds associated with the Mn(4)CaO(5) cluster using a qu...
