Abstract
Solar energy is converted to chemical energy by light-driven water oxidation catalyzed by photosystem II in photosynthetic organisms. Photosystem II requires a complex system of assembly and repair mechanisms to maintain activity and, thus, is found in a variety of precursor states that are not well understood. Here, a cryo-EM structure of photosystem II lacking extrinsic and peripheral subunits, and the cofactor required for water oxidation, is reported. The structure provides insights into the mechanism of photoactivation of photosystem II.
