The role of the 33 kDa protein in Ca2+ binding was studied by comparing the EPR properties of photosystem II in the presence and absence of the 33 kDa protein and Ca2+. When the removal of the 33 kDa protein was carried out in the dark, a normal manganese multiline EPR signal could be observed when the S2 state was generated. In addition, the split S3 signal could not be generated by illumination at 273 K. Exposure of the 33 kDa protein-less photosystem II to room light did not lead to any… CONTINUE READING
