Calcium homeostasis in Escherichia coli
<p>While the role of calcium ions as secondary chemical messengers has been well described in eukaryotic cells, little is known about calcium homeostasis in bacteria at the physiological and molecular level. No calcium influx gene has been identified so far. This dissertation focuses on calcium …

Superoxide Toxicity in Escherichia Coli
Very little is understood about the physiology of the periplasm. of gram negative bacteria. The presence of CuZnSOD within that compartment in several different species suggests that oxidative damage occurs there. We studied the regulation of sodC, the gene that encodes CuZnSOD, and the phenotypes …

Superoxide stress in Escherichia coli
… synthase -- were shown to be inactivated in the Escherichia coli strain which lacks the ability to scavenge O2- (denoted as SOD- mutant). Moreover, the inactivation of DAHP synthase, the first enzyme in the aromatic amino acid biosynthetic pathway, could partially explain the aromatic amino acid …

Biotin synthesis in Escherichia coli
… Thesis, I describe my approaches to delineate Escherichia coli biotin synthetic pathway and to elucidate the roles of BioC and BioH in pimelate synthesis. In Chapter 2, I unravel the synthesis of pimelate. I report in vivo and in vitro evidence that the pimelate intermediate is synthesized by a …

Electrofusion of Escherichia coli with Giant Lipid Vesicles and the Compaction of Escherichia coli Nucleoid
… DASE is applied for inducing the fusion of Escherichia coli-derived biological vesicles and synthetic lipid vesicles and proved to have a great potential as a new tool for delivering bulky cargos into biological vesicles.

Tryptophanase Regulatory Mechanisms in Escherichia coli
… array of bacterial species, but most studied in *Escherichia coli*. Indole is formed by the degradation of L-tryptophan through the action of the enzyme tryptophanase (TnaA). The *tnaA* gene is part of the tryptophanase (*tna*) operon, which is regulated by catabolite repression and …

Rewriting the genome of Escherichia coli
Our recently acquired ability to synthesize DNA at large scale is opening the door to writing entire genomes; this constitutes a powerful approach to address fundamental biological questions, and may enable the creation of designer organisms with useful properties. One interesting avenue for …

Investigation of Escherichia coli [NiFe]-Hydrogenase Maturation
… nickel delivery to the [NiFe]-hydrogenase in Escherichia coli was examined using microbiological, biochemical, spectroscopic, and computational methods. The results demonstrate that protein-protein interactions between the metallochaperones afford layers of nickel selectivity. The protein …

Die Regulation der Transkriptionsantitermination in Escherichia Coli.
… eines Multi-Protein-Komplexes, bestehend aus den Escherichia coli (E. coli) Nus-Proteinen (A, B, E, G), der RNAP, der nut RNA-Sequenz und dem Lambda N-Protein. Die ribosomalen (rrn) Operons in E. coli werden durch intrinsische Antitermination reguliert. Fluoreszenz-Anisotropie-Messungen konnten …

Naujo tetrakatijoninio porfirino sukeltos Escherichia coli fotopažaidos /
The development of multidrug resistance and its spreading among the pathogens, increased the demand for alternative treatment methods of bacterial infections. One of the most promising techniques is photodynamic antibacterial chemotherapy. The main idea of it lays in combining three initially …

The Nature of Uropathogenic Escherichia coli ST127
Uropathogenic Escherichia coli ST127 is a recently emerged clone that is reported to cause a small, but significant, proportion of urinary tract infections. Paradoxically, the low prevalence of ST127 in most published studies is also accompanied by a virulence potential significantly higher than …

Engineering Alkane-Inducible Fimbriation in Escherichia Coli
Fimbriae are small, hair-like appendages arranged on many bacteria’s outer-membrane surfaces used for binding to biotic and abiotic surfaces to resist shear forces and attach to nutrient sources. Fimbriae are important in the initial attachment of cells to a substrate as well as the subsequent …
