ABSTRACT
Chloride is an essential cofactor for the oxidation of water to oxygen. Anion substitution (Br(-), I(-), NO(2)(-), F(-)) in Cl(-)-depleted PS II membranes brings out significant changes in the EPR signals arising from the S(2) state and from the iron-quinone complex of PS II. On the basis of the changes observed in the S(2) state multiline signal and the Q(A)Fe(3+) EPR signal in Cl(-)-depleted PS II membranes after substituting with various anions, we report a possible binding site of anions such as chloride and bromide at the PS II donor side as well as at the acceptor side.
