Genome sequence of <i>Escherichia coli</i> 536: insights into uropathogenicity through comparison with genomes of <i>Escherichia coli</i> MG1655, CFT073, and EDL933
(2006-02-09)Uropathogenic Escherichia coli (UPEC) strain 536 (O6:K15:H31) is one of the model organisms of extraintestinal pathogenic E. coli. To analyze this strain s genetic basis of ... -
Isolierung von DNA und Konstruktion einer Metagenombank aus dem Sediment des Flusses Leine: partielle Sequenzierung und Annotation des Metagenoms sowie Analyse der mikrobiellen Diversität
(2006-01-17)Isolation of environmental DNA, subsequent construction of metagenomic libraries, or amplification and cloning of 16S rRNA genes, and final sequencing of cloned DNA allow phylogenetic and ... -
Charakterisierung von funktionellen Oberflächenstrukturen des Hepatitis-B-Virus Nukleokapsids
(2005-12-28)During hepatitis B virus (HBV) morphogenesis the transmembrane large envelope protein (L protein) probably directly interacts with mature cytosolic nucleocapsids. The shell of the capsid ... -
The PHD finger protein 5 is a part of the spliceosome and acts as a DNA-binding protein
(2005-12-06)Four proteins namely U2AF35, SRp40, mDomino and Ddx1 were identified as PHF5a interacting partners by using the murine 11.5-days embryo yeast two-hybrid library screening.PHF5a interacting ... -
Regulation of Flo11p-dependent adhesion in <i>Saccharomyces cerevisiae</i>
(2005-11-17)In der Bäckerhefe Saccharomyces cerevisiae kodiert FLO11 für ein Zell-Oberflächenprotein. Dessen Expression wird von verschiedenen Umweltbedingungen, wie Glukose-, Stickstoff- oder ... -
Regulation of gene expression and adhesion in <i>Saccharomyces cerevisiae</i>
(2005-11-16)Adherence represents one important and initial virulence factor of fungal pathogenicity. In the model fungus Saccharomyces cerevisiae adherence to substrates or to other cells ... -
Untersuchungen von Cytoskelett-Komponenten und Motilität bei Mycoplasma pneumoniae
(2004-09-29)The cell structure of the bacterium Mycoplasma pneumoniae was investigated by electron- and light-microscopic methods. Ultrastructural details of the cytoskeleton of M. pneumoniae were ... -
Konstruktion eines bakteriellen Systems zum Export von Coenzym B<sub>12</sub>
(2003-11-04)B12 is exclusively synthesized in the cytoplasm of some Bacteria and Archaea. More than 30 different enzymes are involved in the synthesis of this coenzyme. A natural export system for ... -
Localization and Stability of the Transcriptional Activator Gcn4p of Saccharomyces cerevisiae
(2003-02-27)The «general amino acid control« (GAAC) of the yeast Saccharomyces cerevisiae is a well characterized regulatory network which secures a sufficient amino acid supply of the organism. This ... -
Subcellular Localization of Nicotiana tabacum TGA Transcription Factors
(2003-02-11)Salicylic acid (SA) is an important signaling molecule in the regulation of plant defense against pathogens. as-1-like cis-elements in the promoters of many defense genes mediate SA- and ... -
Umwelt-Genomik als Quelle für die Isolierung von neuen Operons und Genclustern aus mikrobiellen Konsortien
(2002-10-15)The main goal of the present work was the isolation of biotin biosynthesis genes and operons from microbial consortia employing a combined enrichment and direct cloning strategy. Cosmid ... -
DAHP Synthasen aus Pilzen
(2002-07-09)The first step of the biosynthesis of the aromatic amino acids is the condensation of erythrose-4-phosphate and phosphoenolpyruvate to 3-deoxy-D-arabino-heptuloso-nate 7-phosphate. This ... -
Identifizierung und Charakterisierung von thermostabilen Uracil Glykosylasen von Archaeon Methanobacterium thermoautotrophicum und Bakterium Thermus thermophilus
(2002-05-22)Hydrolytic deamination reactions of cytosine and 5-methylcytosine results in highly mutagenic U/G and T/G mismatches, respectively. These processes are especially pronounced at high ... -
Analyse des Transkriptionsfaktors TGA2.1 aus Nicotiana tabacum
(2002-04-02)The thesis explores the possible function of the plant transcription factor TGA2.1. For this purpose genetically modified plants were generated in which a) TGA2.1 was ectopically overexpressed ... -
Regulation of nitrogen fixation in Klebsiella pneumoniae: NifL, one protein transducing two environmental signals to the nif-transcriptional activator NifA
(2002-01-15)Klebsiella pneumoniae, NifL modulates the activity of the transcriptional activator NifA in response to combined nitrogen or external molecular oxygen. We recently showed that K. pneumoniae ... -
