HaloTag-Based Tools for Live-Cell Imaging and Elucidation of Organellar Redox Biology

Redox homeostasis is a key factor in maintaining cellular function and health. The main determinant of the intracellular redox potential is ubiquitous glutathione (GSH) together with its oxidized dimer (GSSG). Importantly, both redox equilibrium and GSH ho ...

A Microfluidic Platform Enables Large-Scale Single-Cell Screening to Identify Genes Involved in Bacterial Persistence

Amanda Verpoorte

Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...

Study of transposon-mediated cell pool and cell line generation in CHO cells

Sowmya Balasubramanian

The goal of this thesis was to evaluate the use of artificial transposon systems for the generation of recombinant cell pools and cell lines with Chinese hamster ovary (CHO) cells as the production host. Transposons are naturally occurring genetic elements ...

Randomized codon mutagenesis reveals that the HIV Rev arginine-rich motif is robust to substitutions and that double substitution of two critical residues alters specificity

Maroun Bou Sleiman

The binding of the arginine-rich motif (ARM) of HIV Rev protein to its high-affinity site in stem IIB in the Rev response element (RRE) initiates assembly of a ribonucleoprotein complex that mediates the export of essential, incompletely spliced viral tran ...

TransFLP - A Method to Genetically Modify Vibrio cholerae Based on Natural Transformation and FLP-recombination

Melanie Blokesch

Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...

Single-Cell Analysis of Mycobacterial Persistence Using Microfabricated Tools

Meltem Elitas

Bacterial cells behave as individuals despite being genetically identical and subject to the same environment. Although the underlying mechanisms of cellular individuality are not well understood, temporal variation of gene expression and protein levels in ...

Engineering of the human O6-alkylguanine DNA alkyltransferase

Alexandre Juillerat

Recently, a new method for the specific covalent labeling of fusion proteins in vitro and in living cells has been developed. This method is based on the unusual mechanism of a DNA repair protein: the O6-alkylguanine DNA alkyltransferase (AGT). In addition ...

The Eukaryotic Promoter Database EPD: the impact of in silico primer extension

Philipp Bucher, Rouayda Cavin Perier

The Eukaryotic Promoter Database (EPD) is an annotated non-redundant collection of eukaryotic POL II promoters, experimentally defined by a transcription start site (TSS). There may be multiple promoter entries for a single gene. The underlying experimenta ...

Exploring the Capabilities of Nucleic Acid Polymerases by Use of Directed Evolution

Kai Johnsson, Petra Tafelmeyer

A review. Directed evolution consists of repetitive cycles of random mutagenesis of the protein/peptide sequence followed by screening or selection of candidates with desired properties. Many different approaches are used to introduce mutations into a gene ...

Assembly of type 1 pili in Escherichia coli

Christian Heinis

An extensive random mutagenesis study on the function of nine residues in the subunit binding site of FimC was conducted to evaluate the mol. mechanisms of subunit binding by FimC and the contribution of chaperone surface residues. Five plasmid libraries o ...
