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 ... -
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 ... -
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 ... -
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 ...
