Abstract

It is shown that the compound responsible for the ESR Signal II is localized close to the water-splitting complex and its oxidized state is responsible for the paramagnetic properties. By comparison of the influence of the PS2 electron donors and acceptors on the 1/T1 values of chloroplasts, subchloroplast particles and the exogenous Mn2+-PPC I and Mn2+-PPC II complexes, the major contribution to 1/T1 by the Mn pool of the water-splitting complex, containing the Mn ions in a variety of oxidation states, is established.
