Journal ArticleDOI
Molecular interference of Cd2+ with Photosystem II
TL;DR: Overall electron transfer and partial electron transfer were studied by a combination of EPR spectroscopy of individual redox components, flash-induced variable fluorescence and steady state oxygen evolution measurements, and both Ca2+ and DCMU abolished Cd2+-induced effects partially and in different sites.
Journal ArticleDOI
A five-coordinate Mn( iv ) intermediate in biological water oxidation: spectroscopic signature and a pivot mechanism for water binding
Marius Retegan,Vera Krewald,Fikret Mamedov,Frank Neese,Wolfgang Lubitz,Nicholas Cox,Dimitrios A. Pantazis +6 more
TL;DR: The identification of a unique intermediate in biological water oxidation establishes the water binding mechanism in the S2 to S3 state transition.
Journal ArticleDOI
Quantification of photosystem I and II in different parts of the thylakoid membrane from spinach.
TL;DR: The results suggest that PSI in grana margins have two additional light-harvesting complex II (LHCII) trimers per reaction center compared toPSI in stroma lamellae, and that PSII ingrana has four LHCII trimer per monomer compared to PS II in stromae.
Journal ArticleDOI
Photodamage of iron-sulphur clusters in photosystem I induces non-photochemical energy dissipation.
Arjun Tiwari,Fikret Mamedov,Michele Grieco,Marjaana Suorsa,Anjana Jajoo,Stenbjörn Styring,Mikko Tikkanen,Eva-Mari Aro +7 more
TL;DR: It is demonstrated that the iron–sulphur clusters of PSI are more sensitive to high light stress than previously anticipated, but PSI with damaged FeS clusters still functions as a non-photochemical photoprotective energy quencher (PSI-NPQ).
Journal ArticleDOI
Dimeric and monomeric organization of photosystem II. Distribution of five distinct complexes in the different domains of the thylakoid membrane.
Ravi Danielsson,Marjaana Suorsa,Virpi Paakkarinen,Per-Åke Albertsson,Stenbjörn Styring,Eva-Mari Aro,Fikret Mamedov +6 more
TL;DR: Steady state electron transfer, flash-induced fluorescence decay, and EPR analysis revealed that nearly all of the dimeric forms represent oxygen-evolving PSII centers, and a large fraction did not evolve oxygen.
