Bookmark or Share- RpoS, the Stress Response Sigma Factor, Plays a Dual Role in the ...RpoS, Escherichia coli 's general stress response sigma factor, regulates error-prone DNA polymerase IV (Pol IV) (encoded by the dinB gene). Pol IV is induced in stationary-phase cells, and thereafter, levels of the protein remain elevated for several days of continuous incubation.
- RpoS role in antibiotic resistance, tolerance and persistence inIn the present study, we examined the relationship between intrinsic RpoS levels, in a collection of 328 E. coli natural isolates, and bacterial susceptibility to 15 different antibiotics.
- RpoS and the bacterial general stress responseThe 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.
- What Is the Difference Between RTOs and RPOs? | CrashPlanIn short, the difference between disaster recovery RTOs and RPOs comes down to RPOs being focused on preventing an unacceptable amount of data loss, while RTOs are focused on ensuring your team has a benchmark and can recover from a disaster within an acceptable time frame.
- rpoS - WikipediaThe gene rpoS (RNA polymerase, sigma S, also called katF) encodes the sigma factor sigma-38 (σ38, or RpoS), a 37.8 kD protein in Escherichia coli. [2] Sigma factors are proteins that regulate transcription in bacteria .
