In vivo and ex vivo regulation of bacterial virulence gene expression.
Current Opinion in Microbiology, 1998Bacteria are remarkably adaptable organisms that are able to survive and multiply in diverse and sometimes hostile environments. Adaptability is determined by the complement of genetic information available to an organism and by the mechanisms that control gene expression.

Bacterial lipases from Pseudomonas: regulation of gene expression and mechanisms of secretion.
Biochimie, 2000Lipases from Pseudomonas bacteria are widely used for a variety of biotechnological applications. Overexpression in heterologous hosts like Escherichia coli failed to produce enzymatically active lipase prompting to study the molecular mechanisms underlying the regulation of lipase gene expression and secretion. The prototype lipase from P.

Crystallization of Hfq protein: a bacterial gene-expression regulator
Acta Crystallographica Section D Biological Crystallography, 2003Hfq protein from Escherichia coli (EcoHfq) has been overproduced in E. coli, purified to homogeneity and crystallized using the hanging-drop vapour-diffusion technique. Crystallization conditions for EcoHfq were found which yielded X-ray quality crystals.

Noise in bacterial gene expression.
Biochemical Society Transactions, 2019The expression level of a gene can fluctuate significantly between individuals within a population of genetically identical cells. The resultant phenotypic heterogeneity could be exploited by bacteria to adapt to changing environmental conditions.

Regulation of bacterial gene expression by ribosome stalling and rescuing
Current Genetics, 2015Ribosome is responsible for protein synthesis and is able to monitor the sequence and structure of the nascent peptide. Such ability plays an important role in determining overall gene expression profile of the bacteria through ribosome stalling and rescuing.

Molecular Microbiology, 1990
SummaryThere has been a recent revival of interest in one of the most abundant Escherichia coli proteins, H1 (also called H‐NS). This protein was first identified many years ago as a major component of the bacterial nucleoid, and has been characterized biochemically by several groups.

Metal Regulation of Gene Expression in Bacterial Systems
1998Metals are important in biochemical processes (da Silva and Williams, 1991). They can be cofactors of enzymatic reactions or they can be the key redox components of electron transport processes. Zinc is an example of a metal whose properties as a Lewis acid are used in the reactions of a wide variety of catalytic processes, and a quick glance through a

DNA Supercoiling as a Regulator of Bacterial Gene Expression
1987Studies of gene expression have advanced to a stage at which we can ask quite detailed questions about the factors that influence transcription and the ways in which these factors interact with each other. Such factors include not only the specific proteins that bind to regulatory sites on DNA, but also more subtle aspects of DNA structure, such as ...

Bacterial expression system with tightly regulated gene expression and plasmid copy number
Gene, 2004A new Escherichia coli host/vector system has been engineered to allow tight and uniform modulation of gene expression and gamma origin (ori) plasmid copy number. Regulation of gamma ori plasmid copy number is achieved through arabinose-inducible expression of the necessary Rep protein, pi, whose gene was integrated into the chromosome of the host ...
