|Mathematical Models for the pH Dependence of Oxygen Evolution under Fluoride Inhibition and Effects of Nitrite on Oxygen Evolution in Photosystem II
||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...
|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...
