Concentration matters!! ppGpp, from a whispering to a strident alarmone

Molecular Microbiology, 2011
SummaryBacteria have developed sophisticated signal transduction pathways to sense and respond to environmental stresses. These pathways include intracellular regulators that elicit adaptive changes in the physiology of the cell. Extensive work, mostly performed in Escherichia coli, showed that the modified nucleotide ppGpp plays a key regulatory role ...

Do stalled replication forks synthesize a specific alarmone?

Journal of Theoretical Biology, 1983
Potential causes of premature arrest of a replication fork in vivo include an encounter with a chemical lesion in the DNA, inhibition of one of the essential enzymes of the fork, and spontaneous failure of the fork due to its finite degree of processivity.
