- Researchers isolated and determined a high-resolution cryo-EM structure of intact, oxygen-evolving Photosystem II from Arabidopsis thaliana at 2.44 Å.
- This structure reveals detailed water networks around key sites like the manganese cluster and proton channels, allowing comparison with cyanobacterial PSII.
- The study provides insights into protein-water-cofactor interactions in water splitting, quinone reduction, and the role of lipids at the PSII-light-harvesting interface.
