Identification and Characterization of RpoS Regulon and RpoS-Dependent Promoters in Burkholderia pseudomallei

Journal of Proteome Research, 2009
RpoS subunit of RNA polymerase is a bacterial alternative sigma factor and major regulator important for response to a variety of stress conditions. However, RpoS-dependent genes in Burkholderia pseudomallei remained undefined. We identified the RpoS regulon of B.

Controlled induction of the RpoS regulon inEscherichia coli, using an RpoS-expressing plasmid

Canadian Journal of Microbiology, 2003
RpoS, an alternative sigma factor produced by many Gram-negative bacteria, primarily controls genes that are expressed in stationary phase in response to nutrient deprivation. To test the idea that induction of RpoS in the exponential phase, when RpoS is not normally expressed, increases RpoS-dependent gene expression, we constructed a plasmid carrying

Role of GacA, LasI, RhlI, Ppk, PsrA, Vfr and ClpXP in the Regulation of the Stationary-Phase Sigma Factor rpoS/RpoS in Pseudomonas

Archives of Microbiology, 2003
RpoS is the stationary phase sigma factor responsible for increased transcription of a set of genes when bacterial cells enter stationary phase and under stress conditions.

Elucidating the Function of the RpoS Regulon

Future Microbiology, 2014
Bacterial adaptation to suboptimal nutrient environments, including host and/or extreme environments, is subject to complex, coordinated control involving many proteins and RNAs. Among the γ-proteobacteria, which includes many pathogens, the RpoS regulon has been a key focus for many years.

Polymorphism in the yclC-rpoS Region of Enterobacteria

Current Microbiology, 2003
The nucleotide sequence downstream from the rpoS gene in Enterobacter cloacae and Kluyvera cryocrescens contains the slyA-pad1-yclC genes. The DNA sequence of Enterobacter cloacae CETC960 shows a 2.6-kb insertion of unknown origin between rpoS and slyA.

RpoS and the bacterial general stress response

Microbiology and Molecular Biology Reviews
SUMMARY The general stress response (GSR) is a widespread strategy developed by bacteria to adapt and respond to their changing environments. The GSR is induced by one or multiple simultaneous stresses, as well as during entry into stationary phase and leads to a global response that protects cells against multiple stresses.

A straightforward assay for measuring glycogen levels and RpoS

Journal of Microbiological Methods, 2018
Cellular glycogen levels reflect the activity of RpoS, an important stress-inducible bacterial sigma factor known to regulate several stress-resistance related genes, such as katE, encoding hydroperoxidase II (HPII), and the glg genes, encoding glycogen synthesis enzymes, in Escherichia coli.

Enterobacter cloacae rpoS promoter and gene organization

Archives of Microbiology, 2002
The upstream region of the Enterobacter cloacae strain CECT960 rpoS gene was sequenced. An IS 10R element was found within the nlpD gene, between rpoSp and rpoS. The rpoS promoter, although functional, did not drive transcription of the gene in this strain.

The Role of RpoS in Bacterial Adaptation

2008
Bacterial adaptation to changing conditions and to the host environment requires coordinated changes in gene expression that permit more efficient use of metabolites and increased survival. An important form of gene control is through the use of alternative sigma factors that direct RNA polymerase to recognize a distinct group of genes.
