Molekulare, biochemische und strukturelle Untersuchungen an amylolytischen Enzymen von Thermotoga maritima MSB8
(2001-08-01)One of the most thermophilic and ancient bacteria known to date, the hyperthermophilic Thermotoga maritima MSB8 (growth range: 55°C - 90°C), degrades and fermentatively utilizes organic ... -
Physiologische Untersuchungen zur Regulation des Aminosäure-Stoffwechsels von Bacillus licheniformis DSM13
(2011-05-05)In contrast to his close relatives Bacillus licheniformis is able to grow fermentative under strict anaerobic conditions. Investigations of the anaerobic growth in a defined medium have ... -
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 ... -
Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: Nitrogen and oxygen signal perception by the negative regulator NifL
(2008-08-08)In the diazotroph Klebsiella pneumoniae, the nif specific transcriptional activator NifA is inhibited by the flavoprotein NifL in response to molecular oxygen and ammonium. We demonstrated ... -
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 ... -
Saccharomyces cerevisiae DNA helicases Mph1, Srs2 and Sgs1 collaborate for the reinitiation of stalled or collapsed replication forks
(2006-08-10)The MPH1 gene from Saccharomyces cerevisiae codes for a DNA helicase involved in the error-free bypass of DNA lesions via homologous recombination. Simultaneous deletion of the MPH1 and ... -
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 ... -
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 ... -
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 ... -
Untersuchung der Stressantwort von <i>Picrophilus torridus</i> mittels 2D-Gelelektrophorese und Charakterisierung ausgewählter Dehydrogenase
(2008-07-09)The thermoacidophilic archaeon Picrophilus torridus belongs to the Thermoplasmatales and is the most acidophilic microbe yet known. Optimal living conditions are at 60°C and pH 0.7. Some ... -
Untersuchung zur wechselseitigen Beeinflussung von Chemotaxinen und Dendritischen Zellen
(2008-04-01)Prostaglandin (PG) E2 and IL-4 have been implicated in maturation of DC and in the modulation of DC migration. In the present study, IL-4 as well as IL-13 were found to impair migration of murine DC and macrophages in ... -
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 ... -
Untersuchungen zur genetischen Regulation der CO<sub>2</sub>-Assimilation in <i>Ralstonia</i> spp.
(2006-05-02)Autotrophic CO2 assimilation in Ralstonia eutropha H16 and Ralstonia metallidurans CH34 involves the enzymes of the Calvin-Benson-Bassham (CBB) cycle. The expression of the two ... -
Übertragung von BSE auf nicht humane Primaten als Modell für die variante Creutzfeldt-Jakob Erkrankung (vCJD) im Menschen
(2007-06-05)The EU-study QLK1-CT-2002-01096 was designed to assess the risk of vCJD (variant Creutzfeldt-Jakob disease) infection in humans via BSE-contaminated food in an animal model. Groups of six ... -
