Alkaline phosphatase as a reporter of sigma(S) levels and rpoS polymorphisms in different E-coli strains
(SPRINGER, 2008)
sigma(S) is responsible for the transcriptional regulation of genes related to protection against stresses and bacterial survival and it accumulates in the cell under conditions of stress, such as nutrient limitation. An ...
Strain variation in ppGpp concentration and RpoS levels in laboratory strains of Escherichia coli K-12
(SOC GENERAL MICROBIOLOGY, 2008)
Laboratory strains and natural isolates of Escherichia coli differ in their level of stress resistance due to strain variation in the level of the sigma factor sigma(S) (or RpoS), the transcriptional master controller of ...
The constancy of global regulation across a species: the concentrations of ppGpp and RpoS are strain-specific in Escherichia coli
(BIOMED CENTRAL LTD, 2011)
Background: Sigma factors and the alarmone ppGpp control the allocation of RNA polymerase to promoters under stressful conditions. Both ppGpp and the sigma factor sigma(S) (RpoS) are potentially subject to variability ...

RpoS and RpoN are involved in the growth-dependent regulation of rfaH transcription and O antigen expression in Salmonella enterica serovar typhi
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004-01)
We reported earlier that the production of 0 antigen lipopolysaccharide (LPS) by Salmonella enterica serovar Typhi (Salmonella typhi) increases at the onset of stationary phase and correlates with a growth-regulated ...
The uncertain consequences of transferring bacterial strains between laboratories - rpoS instability as an example
(2011-11-08)
Abstract
Background
Microbiological studies frequently involve exchanges of strains between laboratories and/or stock centers. The integrity of exchanged strains is vital for ...

The alternative sigma factor, σS, affects polyhydroxyalkanoate metabolism in Pseudomonas putida
(Wiley Blackwell Publishing, Inc, 2008-07)
To determine whether the stationary sigma factor, σS, influences polyhydroxyalkanoate metabolism in Pseudomonas putida KT2440, an rpoS-negative mutant was constructed to evaluate polyhydroxyalkanoate accumulation and ...
