Acyl-acyl carrier protein synthetases from bluegreen algae and plants
(2008-12-02)All metabolic processes involving fatty acids are preceded by the activation of the fatty acid to form a thioester derivative. Activation by acyl-CoA synthetase is well established whereas ... -
Biochemische Charakterisierung von PpoA aus Aspergillus nidulans
(2010-02-17)In the present work Psi-factor- producing oxygenases from Aspergillus nidulans, so called Ppo-enzymes have been studied and characterized. These enzymes are known to possess regulatory ... -
Evaluierung des Antibody Directed Enzyme Prodrug Therapy-Konzepts im Mammakarzinom- und Lymphom-Mausmodell
(2007-10-31)The aim of this study was in vivo evaluation of a new tumor therapy called Antibody Directed Enzyme Prodrug Therapy (ADEPT). This therapy should give a high specificity and selectivity for ... -
Fettsäuretransport in die peroxisomale Matrix von <i>Arabidopsis thaliana</i>
(2007-08-15)Fatty acids are essential components of living organism. The distribution of fatty acids between cells as well as within a cell is a complex process due to their low solubility in water. ... -
Identifizierung und funktionale Charakterisierung neuartiger Acyltransferasen aus Mikroalgen
(2009-12-04)A more sustainable access to alternative sources for very long chain polyunsaturated fatty acid (VLCPUFA) containing oils becomes more important as a human diet enriched in n-3 fatty is ... -
Mobilisierung von Speicherlipiden in <i>Cucumis sativus</i>- und <i>Arabodopsis thaliana</i>-Keimlingen
(2008-12-12)Germination of oilseeds is characterized by mobilisation of TAGs that are stored in lipid bodies and serve as carbon source. Beside the classical degradation pathway of these storage ... -
Ein neuer Syntheseweg für wertvolle Fettsäuren in Saccharomyces cerevisiae und Arabidopsis thaliana
(2009-04-03)The production of very long chain fatty acids (VLCPUFAs) with relevance for human nutrition in transgenic oilseeds represents a major challenge for plant biotechnology. Up to now, VLCPUFA ... -
New fatty acids, oxylipins and volatiles in microalgae
(2007-11-26)The main objective of the present thesis was the identification of microalgae producing compounds of high value, in particular polyunsaturated fatty acids (PUFAs) and oxylipins which might ... -
Oxylipinstoffwechsel in Physcomitrella patens
(2011-07-01)During the presented doctoral thesis enzymes of the oxylipin metabolism from P. patens have been purified & described. Therefore, the bifunctional PpLOX1 & two AOC enzymes (PpAOC1 & PpAOC2) ... -
Phenylpropanoids and long chain fatty acid derivatives in the interaction of <i>Arabidopsis thaliana</i> and <i>Verticillium longisporum</i>
(2012-10-02)Verticillium longisporum is a soil borne pathogen which infects plants of the Brassicaceae family. The fungus enters through the roots and spreads within the plant through the xylem. Using the model plant Arabidopsis ... -
Role of miRNAs in Oligodendrocyte Development
(2010-09-10)MicroRNAs (miRNAs) are important for the regulation of various processes in cell biology. However, the function of miRNAs in the central nervous system and especially in glial cells is still ... -
Signals and metabolic consequences during the interaction of Brassicaceae and <i>Verticillium longisporum</i>
(2013-01-14)The soil-borne, hemibiotrophic pathogen Verticillium longisporum is a severe threat for oilseed rape (Brassica napus) cultivation. In order to develop effective, defensive treatments for infected plants a thorough understanding ... -
Sphingolipids in <i>Physcomitrella patens</i>
(2019-05-10)The model organism Physcomitrella patens is a bryophyte in the group of non-vascular plants. Evolutionary, bryophytes evolved shortly after the event when plants developed the ability to grow on land. P. patens can therefore ... -
Structure and function of A.nidulans PSI factor producing oxygenase A
(2013-04-25)Phytopathogenic fungi are not only of economic importance for the yield depression they cause, but can also be considered as severe threat for the health of the consumer ingesting molded crops and fruits. This health threat ... -
The production of VLCPUFAs in plants
(2011-03-17)Very long-chain polyunsaturated fatty acids (VLCPUFAs) like eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) are health-beneficial components in the human diet. However, due to ... -
Untersuchungen zum Fettsäuretransport durch zelluläre und peroxisomale Membranen
(2010-11-12)Despite intensive research and numerous publications the precise mechanism by which free fatty acids cross the plasma membrane is still controversial. Within this work we addressed the ...
