Regulation of glucosamine-6-phosphate synthase synthesis by a hierarchical acting cascade composed of two small regulatory RNAs in <i>Escherichia coli</i>.
(2010-04-14)Amino sugars are essential for the biosynthesis of the bacterial cell wall and of lipopolysaccharides. The enzyme glucosamine-6-phosphate synthase (GlmS) catalyzes the formation of ... -
Regulation der Glutamatsynthese in Bacillus subtilis durch die Glutamatdehydrogenase RocG und das Aktivatorprotein GltC
(2006-11-20)Bacillus subtilis is able to utilize a huge number of carbon sources. For efficient utilization of a carbon source both, carbon and nitrogen metabolism, have to be well coordinated. ... -
Entschlüsselung der Genome von <i>Ralstonia eutropha</i> H16 und <i>Methanosphaera stadtmanae</i> und vergleichende Untersuchungen zu Anpassungen der Genomorganisation
(2006-04-04)The genomes of two micoorganisms - Ralstonia eutropha H16 and Methanosphaera stadtmanae - have been sequenced with the whole-genome shotgun approach and analysed with special emphasis on genomic ... -
Untersuchungen zu Struktur-Funktionsbeziehungen in der tRNA-ähnlichen Struktur des Rüben-Gelbmosaik-Virus
(2004-04-16)The Turnip-Yellow-Mosaic-Virus (TYMV) is a (+)-strand RNA-virus which infects plants of the Brassicaceae family. Its genome of 6318 nucleotides (nt) length contains a tRNA-like ... -
Konstruktion und Durchmusterung von Metagenombanken: Identifizierung und Charakterisierung von Genen und Genprodukten von am Polyol-Stoffwechsel beteiligten Oxidoreduktasen und Coenzym B12-abhängigen Dehydratasen
(2004-01-21)A new way to exploit the metabolic and genetic diversity of microorganisms is the construction of DNA libraries directly from environmental samples. To isolate new genes encoding coenzyme ... -
Die vollständige Entschlüsselung der Genomsequenz des Tetanus-Erregers <i>Clostridium tetani</i> und die Analyse seines genetischen Potentials
(2003-08-22)The Gram-positive bacterium Clostridium tetani is an endospore-forming organism predominantly found in anaerobic zones of soil. In deep wound infections C. tetani can produce a potent ... -
Yeast Chorismate Mutase: Molecular Evolution of an Allosteric Enzyme
(2003-01-30)Chorismate mutase (CM, EC 5.4.99.5), encoded by ARO7, catalyzes the Claisen rearrangement of chorismate to prephenate in the biosynthesis of the amino acids tyrosine and phenylalanine. The ... -
CHARACTERIZATION OF BACTERIAL LIPOPOLYSACCHARIDES (Pseudomonas syringae pv. tomato and Pseudomonas syringae pv. apii) AND PECTINS OF TOMATO AND CELERY PLANTS (Lycopersicon esculentum and Apium graveolens) REGARDING THEIR POSSIBLE ROLE IN HOST/PATHOGEN-INTERACTION
(2002-10-15)All plants face a formidable challenge of defending themselves against a large number of pathogens. The interactions between a pathogen and its host are governed by a number of factors. ... -
Produktion von monoklonalen Antikörpern und Phagenantikörpern gegen das Rinder-Prionprotein durch SFV Partikel-vermittelte Immunisierung von PrP0/0-Mäusen
(2002-01-16)The aim of my graduation work was the production and characterisation of monoclonal antibodies (mAK) and phage antibodies against the bovine Prionprotein (PrP). In the first part of the ... -
Untersuchungen zur Inaktivierung und Reaktivierung der Coenzym B12-abhaengigen Glycerin-Dehydratasen aus Citrobacter freundii und Clostridium pasteurianum
(2002-01-11)The coenzyme B12-dependent glycerol dehydratase of Citrobacter freundii is subject to suicide inactivation by the natural substrate glycerol during catalysis. We identified dhaF and dhaG ... -
Zur Struktur und Funktion regulatorischer Elemente des cbb-Regulons in Ralstonia eutropha
(2001-11-13)For autotrophic CO2 assimilation Ralstonia eutropha H16 requires the enzymes of the Calvin cycle. The genetic control involved in the adjustment of carbon metabolism between ... -
Chromatinstruktur und Regulation der Genexpression am Histidin/Adenin-Verzweigungspunkt in Hefe und Aspergillus
(2001-10-23)Imidazole glycerole phosphate (IGP) synthase (E.C.2.4.2. & E.C.4.3.2.4) catalyzes the fifth and the sixth reaction step of the histidine biosynthesis. The byproduct of the reactions, AICAR, ...
