Photosynthesis produces dioxygen at photosystem II (PSII), which is located in the thylakoid membrane of plant chloroplasts. Chloride (Cl-) is required for oxygen evolution activity and other anions are known to activate or inhibit O2 evolution. In t... |

Photosystem II (PSII) is the light-harvesting water oxidase of thylakoid membranes. The catalytic center where oxygen forms in PSII is located at the manganese cluster, Mn4O5Ca, which is highly conserved throughout nature as seen in cyanobacteria and... |
| Investigation of dialysis methods for the complete removal of Cl- from photosystem II |

"Photosystem II (PSII), which produces oxygen using light energy, requires Cl- as a cofactor. Cl- appears to be difficult to remove from PSII because there always remains residual activity of 25-40%. We have tested variations of the dialysis method t... |
| Chloride requirement in photosystem II and anion effects in the S2' state of the oxygen evolving complex |

"The oxygen evolving complex (OEC) of photosystem II (PSII) requires chloride as a critical cofactor. The Cl- content of PSII was determined to be 1 Cl-/PSII by the AgCl colloid assay. The dissociation constant for Cl- in NaCl-washed PSII was determi... |

Photosystem II (PSII) is the membrane-bound protein complex which participates in the photosynthetic conversion of sunlight energy into chemical energy and produces molecular oxygen. Calcium and chloride are important cofactors that PSII requires in ... |
