- rpoS - Wikipedia
Sigma factors are proteins that regulate transcription in bacteria Sigma factors can be activated in response to different environmental conditions rpoS is transcribed in late exponential phase, and RpoS is the primary regulator of stationary phase genes
- RpoS role in antibiotic resistance, tolerance and persistence . . .
The role of RpoS in antibiotic resistance and persistence in standard laboratory domesticated strains has been examined in several studies, most demonstrating a positive role for RpoS
- RpoS and the bacterial general stress response | Microbiology . . .
The alternative sigma factor RpoS is the central GSR regulator in E coli and conserved in most γ-proteobacteria In E coli, RpoS is induced under conditions of nutrient deprivation and other stresses, primarily via the activation of RpoS translation and inhibition of RpoS proteolysis
- The RpoS-mediated general stress response in Escherichia coli
Under conditions of nutrient deprivation or stress, or as cells enter stationary phase, Escherichia coli and related bacteria increase the accumulation of RpoS, a specialized sigma factor RpoS-dependent gene expression leads to general stress resistance of cells
- Regional Passport Office Contact Numbers and Timings
What is a Regional Passport Office (RPO)? A Regional Passport Office (RPO) is a central government office under the Ministry of External Affairs (MEA) that manages all passport-related services in its jurisdiction
- Stress sigma factor RpoS degradation and translation are . . .
RpoS, the stationary phase stress sigma factor of Escherichia coli, regulates a large cohort of genes important for the cell to deal with suboptimal conditions Its level increases quickly in the cell in response to many stresses and returns to low levels when growth resumes
- rpoS Mutations and Loss of General Stress Resistance in . . .
In this study, we investigated the selective advantage of losing RpoS and whether RpoS contributes to fitness under nutrient limitation Reduced growth rates controlled by the availability of glucose or a nitrogen source can be established in continuous cultures or chemostats
- RpoS - an overview | ScienceDirect Topics
RpoS (also called σS or σ38) is a transcription factor of the RNA polymerase highly expressed during stationary phase and in response to multiple stresses, to activate transcription of several hundred genes
