Photosystem II: Difference between revisions

Another important facet of photosystem II is its ability to oxidize water to oxygen with its <scene name='Photosystem_II/Oxygen_evolving_centers/5'>oxygen evolving centers</scene>.  These <scene name='Photosystem_II/Oxygen_evolving_centers/8'>centers</scene> were shown to be cubane-like Mn₃CaO₄cluster linked to a fourth Mn by a mono-μ-oxo bridge.
