N2 - Reconstitution of Mn-depleted PSII particles with synthetic binuclear Mn complexes (one Mn(II)2 complex and one Mn(IV)2 complex) was examined. In both cases the electron-transfer rates in the reconstituted systems were found to be up to 75-82% of that measured in native PSII but the oxygen evolution activity remained lower (<5-40%). However, hydrogen peroxide was also produced by the reconstituted samples. These samples therefore represent a new type of reconstituted PSII that generates hydrogen peroxide as the final product in reconstituted PSII centers.
