Abstract: Proteinphosphorylierungen sind reversible posttranslationale Modifikationen, die oft als molekulare Schalter für biochemische Signalwege dienen. Sie haben wesentlichen Einfluss auf die Regulation der Photosynthese. Vergangene Studien zeigten, dass auch phosphorylierungsbedingte Langzeitanpassungen des plastidären Metabolismus, sowie der chloroplastidären und nukleären Genexpression auftreten können. Um derartige Mechanismen und Knotenpunkte der Signalwege besser zu verstehen, wurden im Rahmen dieser Dissertation Proteinphosphorylierungsstudien am Chloroplasten von Arabidopsis thaliana durchgeführt. Die Ergebnisse dieser Dissertation zeigen, dass die drei Kinasen pCKII, STN7 und STN8 Mediatoren zwischen der photosynthetischen und metabolischen Funktion, sowie der Langzeitanpassung im Chloroplasten sind.
Protein phosphorylations are reversible posttranslational modifications (PTMs), which serve often as molecular switches for biochemical pathways. Their influence on the regulation of photosynthesis is already well known. Former studies show a further influence on long-term acclimations of the plastid metabolism and the plastid and nuclear gene expression. In order to understand such mechanisms and network nodes of the corresponding pathways were phosphorylation studies on the chloroplasts of Arabidopsis thaliana conducted. The results of this thesis show that the three kinases pCKII, STN7 and STN8 are mediators between the photosynthetic and the metabolic function of the chloroplast and its long-term adaptation to prevailing light conditions.
