Metal cluster and tyrosine at the core of O2 creation in photosystem II

Metal cluster and tyrosine at the core of O2 creation in photosystem II

The metal cluster of manganese, calcium and oxygen releases breathable oxygen from water. Tyrosine speeds the flow of electrons across the cluster that powers the multi-step reaction cycle by flipping around, both chemically and physically. The calcium component, depicted here on top of the cluster, appears to have a special interaction with the tyrosine. Credit: Georgia Tech / Barry / Guo
