Calcium homeostasis in Escherichia coli
… role as overactive calcium efflux systems in E. coli. My data also raises the distinct possibility of calcium's involvement in stress response as evidenced by upregulation of marB in transposon mutants and by 10-fold induction of rpoS in elevated calcium condition in mutants defective in calcium …

Superoxide Toxicity in Escherichia Coli
… copper is unavailable. Mutants of sodC in E. coli and S. typhimurium suffer damage during aerobic growth from a cellular source of superoxide. The unknown damage sensitizes the mutants to subsequent challenges with H2O2. This result indicates that there is a role for CuZnSOD other than …

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
… acid. However, the mechanism whereby E. coli assembles this pimelate intermediate was unclear. Genetic analyses identified only two genes of unknown functions, bioC and bioH, which are required for pimelate synthesis. BioC is annotated as an S-adenosyl-L-methionine (SAM) dependent …

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
… reported strategies for genome engineering in E. coli (REXER and GENESIS) are extended and used to create a synthetic, recoded E. coli genome. Chapter 2 describes a strategy for assembling large natural genomic DNA pieces into BACs that are substrates for genome replacement. Experiments with these …

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 …

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
… to a surface. In this investigation, E. coli was engineered to over-express fimbriae in response to the presence of IPTG and DCPK. The over-expression of fimbriae in E. coli resulted in a pronounced response to the agglutination of mannose-containing yeast cells, causing them to sediment …
