The synthesis and function of the alarmone (p)ppGpp in firmicutes

International Journal of Medical Microbiology, 2010
In most bacteria, nutrient limitations provoke the stringent control by the rapid synthesis of the alarmones pppGpp and ppGpp. The most prominent and highly conserved reaction is the repression of rRNA synthesis. Additionally, (p)ppGpp synthesis is also linked to many other physiological changes involving gene activation/repression but also protein ...

Sustained ppGpp production underpins months-long survival of a bacterium in growth arrest

mBio
When growing bacteria start to reach stationary phase, the nucleotide guanosine tetra-phosphate (ppGpp) accumulates intracellularly and regulates the transition of cells from growth to growth arrest.
