AbstractGuanosine 5′‐(tri)diphosphate, 3′‐diphosphate [(p) ppGpp] is a small nucleic acid that helps bacteria survive in limited environments. Gene chip shows that (p) ppGpp is a global transcription‐regulator of genes related to important bacterial metabolic processes.

AbstractIn recent years, emerging and reemerging pathogens resistant to nearly all available antibiotics are on the rise. This limits the availability of effective antibiotics to treat infections, thus it is imperative to develop new drugs. The accumulation of alarmones guanosine tetraphosphate and guanosine pentaphosphate, collectively known as (p ...

The magic dance of the alarmones (p)ppGpp
Molecular Microbiology, 2016SummaryThe alarmones (p)ppGpp are important second messengers that orchestrate pleiotropic adaptations of bacteria and plant chloroplasts in response to starvation and stress. Here, we review our structural and mechanistic knowledge on (p)ppGpp metabolism including their synthesis, degradation and interconversion by a highly diverse set of enzymes ...

Translational accuracy enhanced in vitro by (p)ppGpp
Molecular and General Genetics MGG, 1980The effect of (p)ppGpp on the accuracy of translation in vitro was studied with a system that has a missense error frequency similar to that of living bacteria. When poly (U) is translated, limitation of the system in Phe increases the Leu missense error frequency.
