Ribose lowers RpoS translation through RbsD mRNA

|
By Isabel Smith, Celeste Nora Peterson, Andrew Badaoui, Melisa Balla
| BioRxiv
Abstract The Escherichia coli sigma factor RpoS accumulates during starvation, activates transcription of the general stress response, and then rapidly returns to low levels upon nutrient replenishment. Sugar levels modulate RpoS levels by signaling though central metabolism, ATP and the phosphoenolpyruvate-carbohydrate phosphotransferase system (PTS) transport system, which favors glucose. However, there have been few examples of dedicated control pathways for specific sugars regulating RpoS.
