Journal ArticleDOI
The function of peroxiredoxins in plant organelle redox metabolism
Karl-Josef Dietz,Simone Jacob,Marie-Luise Oelze,Miriam Laxa,Vanesa B. Tognetti,Susana Marina Nunes de Miranda,Margarete Baier,Iris Finkemeier +7 more
TL;DR: Present knowledge on plant organellar Prx is summarized, addressing Prx in signalling, and also suggests some lines for future research.
Journal ArticleDOI
The Role of the Plant Antioxidant System in Drought Tolerance.
TL;DR: The meta-analysis of reported changes in transcript and protein amounts, and activities of components of the antioxidant and redox network support the tentative conclusion that drought tolerance is more tightly linked to up-regulated ascorbate-dependent antioxidant activity than to the response of the thiol-redox regulatory network.
Journal ArticleDOI
S-Nitrosylation of Peroxiredoxin II E Promotes Peroxynitrite-Mediated Tyrosine Nitration
María C. Romero-Puertas,Miriam Laxa,Alessandro Matte,Federica Zaninotto,Iris Finkemeier,Alex M.E. Jones,Michele Perazzolli,Elodie Vandelle,Karl-Josef Dietz,Massimo Delledonne +9 more
TL;DR: It is concluded that NO regulates the effects of its own radicals through the S-nitrosylation of crucial components of the antioxidant defense system that function as common triggers for reactive oxygen species– and NO-mediated signaling events.
Journal ArticleDOI
Proteins of Diverse Function and Subcellular Location Are Lysine Acetylated in Arabidopsis
TL;DR: It was demonstrated that Lys deacetylation significantly affects Rubisco activity as well as the activities of other central metabolic enzymes, such as the Calvin cycle enzyme phosphoglycerate kinase, the glycolytic enzyme glyceraldehyde 3-phosphate dehydrogenase, and the tricarboxylic acid cycle enzyme malate dehydrogensase.
Journal ArticleDOI
Peroxiredoxin Q of Arabidopsis thaliana is attached to the thylakoids and functions in context of photosynthesis.
Petra Lamkemeyer,Miriam Laxa,Valérie Collin,Wen-Xue Li,Iris Finkemeier,Mark Aurel Schöttler,Volker Holtkamp,Vanesa B. Tognetti,Emmanuelle Issakidis-Bourguet,Andrea Kandlbinder,Engelbert Weis,Myroslawa Miginiac-Maslow,Karl-Josef Dietz +12 more
TL;DR: Increased fluorescence ratios of photosystem II to I at 77 K and modified transcript levels of plastid- and nuclear-encoded proteins show that regulatory mechanisms are at work to compensate for the lack of Prx Q.
