Özet

The efficiency of Schiff base manganese complexes in reconstituting Photosystem II (PS II) electron flow and oxygen-evolution capacity was analyzed in PS II deprived of their manganese cluster and the extrinsic regulatory subunits. Three Schiff base complexes, mononuclear Mn(salpn)(2), binuclear [Mn(salpn)](2)(ClO4)(2) and mu-oxo binuclear [Mn(salpn)O](2), salpn: 1,3-bis(salicylideneamino)propane, were used for reconstruction of electron transport and oxygen evolution. Order of reconstruction effect is as follows: mu-oxo binuclear Mn(III) > binuclear Mn(M) > mononuclear Mn(H). (C) 2003 Elsevier B.V. All rights reserved.
