Untangling the sequence of events during the S₂ → S₃ transition in photosystem II and implications for the water oxidation mechanism

In oxygenic photosynthesis, light-driven oxidation of water to molecular oxygen is carried out by the oxygen-evolving complex (OEC) in photosystem II (PS II). Recently, we reported the roomtemperature structures of PS II in the four (semi)stable S-states, S₁, S₂, S₃, and S₀, showing that a water mol...
