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 ... -
Characterisation of the cell wall protein Pga29p in the human pathogenic fungus <i>Candida albicans</i>
(2009-02-17)Candida albicans is an opportunistic fungal pathogen that is responsible for most of the Candida infections in humans. It can cause superficial infections on the mucosa, nails or skin and ... -
Characterization of an Arabidopsis glutaredoxin that interacts with core components of the salicylic acid signal transduction pathway
(2006-05-16)Salicylic acid (SA) is a plant signalling molecule that mediates the induction of defense responses upon attack by a variety of pathogens. Activation sequence-1 (as-1) type cis elements and ... -
Characterization of Synaptotagmin Function In Calcium Dependent Neuronal Exocytosis
(2007-08-17)Synaptotagmin 1 is a synaptic vesicle protein believed to be the calcium sensor at the neuronal synapse. The protein consists of two calcium dependent membrane binding domains known as the ... -
Directed evolution of novel properties starting from HisF of <i>Thermotoga maritima</i> as a structural scaffold
(2006-01-24)tHisF, imidazole glycerol phosphate synthase from hyperthermophilic organism T. maritima, with a (ba)8-barrel structure was used as scaffold for directed evolution of enzymes. The ... -
Distinct roles of PI4P 5-kinase isoforms in polar tip growth of pollen tubes
(2009-08-18)Phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2) occurs in the tip-plasma membrane of growing pollen tubes. Because enzymes responsible for PI(4,5)P2-production at that location are ... -
Evolutive in vitro-Adaption eines thermostabilen, (βα)8-barrel-Proteins an die Katalyse einer abiotischen Reaktion
(2004-02-12)The tHisF, the synthase subunit of the imidazole glycerol phosphate synthase from the hyperthermophilic organism Thermothoga maritima, was used to make the (βα)8-barrel-fold accessible 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. ... -
Functional analysis of the Arabidopsis thaliana glutaredoxin ROXY9
(2019-05-24)Glutaredoxins are nearly ubiquitious small enzymes which protect the thiol groups of cellular proteins from oxidative stress, contribute to iron-sulfur cluster biogenesis or regulate protein activities via redox modification. ... -
Genetic fingerprints of microalgal culture strains: amplified fragment length polymorphism (AFLP) for investigations below the species level
(2006-05-16)The aim of the present thesis was to analyse microalgal culture strains at the level below species. This was important to improve the abilities of service culture collections of algae to ... -
Glycerolmetabolismus und Pathogenität von <i>Mycoplasma pneumoniae</i>
(2008-06-03)Mycoplasma pneumoniae, the causative agent of atypical pneumonia, is able to use glucose and fructose as well as glycerol as sole carbon source. Glycerol is taken up by facilitated diffusion ... -
Identification and Characterization of Novel Genes involved in Quinone Synthesis in the Odoriferous Defensive Stink Glands of the Red Flour Beetle, Tribolium castaneum
(2021-05-26)Defense strategies are common in insects including Coleoptera, the largest animal taxon containing various types of beetles. Stink gland secretion of beetles is playing an important role in their defense against detrimental ... -
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 ... -
Impact of specific long chain acyl CoA synthetases on plant development
(2012-06-18)Fatty acids are essential components of cellular life. However, in their natural form they cannot enter metabolism but in fact they need enzymatic activation by coenzyme A to become metabolically accessible. One enzyme ... -
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 ... -
Molecular analysis of importin-α-mediated nucleocytoplasmic signaling in plant innate immunity
(2015-04-30)IMPORTIN-αs are a family of nuclear transport receptors that mediate the translocation of nuclear localization signal (NLS)-containing cargo proteins from the cytoplasm into the nucleus through nuclear pores. The IMPORTIN-α3, ... -
