The interaction of Cl- with the extrinsic proteins of 18 kDa, 24 kDa and 33 kDa in the photosynthetic oxygen-evolution complex was studied by comparing spinach photosystem II particles of different protein compositions. The 33-kDa protein decreased the Cl- concentration optimum for oxygen evolution from 150 to 30 mM, and the 24-kDa protein decreased it from 30 to 10 mM. The 18-kDa protein did not change the optimum Cl- concentration, but sustained oxygen evolution at Cl- concentrations lower than 3 mM. The presence of the 24-kDa and 18-kDa proteins, but not each protein alone, markedly suppressed inactivation of oxygen evolution at a very low Cl- concentration and its restoration by readdition of Cl-.
