Identification of components of the sigma b regulon in listeria monocytogenes that contribute to acid and salt tolerance
(American Society for Microbiology, 2008-09-19)
Sigma B (sigma(B)) is an alternative sigma factor that controls the transcriptional response to stress in Listeria monocytogenes and is also known to play a role in the virulence of this human pathogen. In the present study ...
Proteomic analyses of a listeria monocytogenes mutant lacking b identify new components of the b regulon and highlight a role for b in the utilization of glycerol
(American Society for Microbiology, 2007-12-07)
In Listeria monocytogenes the alternative sigma factor sigma(B) plays important roles in both virulence and stress tolerance. In this study a proteomic approach was used to define components of the (sigma(B) regulon in L. ...
Role of listeria monocytogenes b in survival of lethal acidic conditions and in the acquired acid tolerance response
(American Society for Microbiology, 2003-05-01)
The food-borne pathogen Listeria monocytogenes can acquire enhanced resistance to lethal acid conditions through multiple mechanisms. We investigated contributions of the stress-responsive alternative sigma factor, or ...
Role of b in regulating the compatible solute uptake systems of listeria monocytogenes: osmotic induction of opuc is b dependent
(American Society for Microbiology, 2003-04-01)
The regulation of the compatible solute transport systems in Listeria monocytogenes by the stress-inducible sigma factor sigma(B) was investigated. Using wild-type strain 10403S and an otherwise isogenic strain carrying ...
Mycosphere essay 10: properties and characteristics of microbial xylanases
(Mushroom Research Foundation, 2016-01-01)
Xylanases are a group of enzymes that hydrolyze xylan which is a primary constituent of hemicellulose, the second most abundant polysaccharide in nature. These enzymes are endo-beta-1,4-xylanases, they include debranching ...
Blue-light inhibition of listeria monocytogenes growth is mediated by reactive oxygen species and is influenced by σband the blue-light sensor lmo0799
(American Society for Microbiology, 2016-04-29)
Listeria monocytogenes senses blue light via the flavin mononucleotide-containing sensory protein Lmo0799, leading to activation of the general stress response sigma factor SigB (sigma(B)). In this study, we investigated ...
Effects of growth phase and temperature onσbactivity within alisteria monocytogenespopulation: evidence for rsbv-independent activation ofσbat refrigeration temperatures
(Hindawi Limited, 2014-01-01)
The alternative sigma factor sigma(B) of Listeria monocytogenes is responsible for regulating the transcription of many of the genes necessary for adaptation to both food-related stresses and to conditions found within the ...
