【Significance】
Magnetic Structure of Manganese Cluster

The great advancements have been achieved to elucidate the photosynthetic oxygen evolution since the discovery of the X-ray crystal fine structure of Photosystem II. However, the mechanism is still under debate. In this review, we reported the electronic structure of manganese cluster in photosystem II investigated by electron paramagnetic resonance spectroscopy. PELDOR measurement was performed to determine the spin density distribution in magnetically coupled Mn in the S2 state Mn cluster. ENDOR signals were assigned to the water molecules ligated to the Mn cluster. The location of a high-affinity Mn2+ site in apo-photosystem II was determined by PELDOR.
