Another important facet of photosystem II is its ability to oxidize water to oxygen with its <scene name='Photosystem_II/Oxygen_evolving_centers/9'>oxygen evolving centers</scene>.  These <scene name='Photosystem_II/Oxygen_evolving_centers/3'>centers</scene> were shown to be a cubane-like structure with a 3 manganese, 4 oxygen and calcium strucure linked to a fourth manganese.^[1] Purple represents manganese, red represents oxygen and green is for calcium.  Oxidation of water to leaves 2 H ⁺ on the lumenal side of the membrane, helping to establish the proton gradient essential for ATP synthesis in the CF₁CF₀-ATP sythase protein.
