ppGpp signaling plays a critical role in virulence of Acinetobacter baumannii

open access: yes, 2021
Acinetobacter baumannii, a major nosocomial pathogen, survives in diverse hospital environments, and its multidrug resistance is a major concern. The ppGpp-dependent stringent response mediates the reprogramming of genes with diverse functions in several

Guanosine tetraphosphate (ppGpp) is a new player in Brassica napus L. seed development

open access: yes
International audienceRapeseed oil, constituting 12% of global vegetable oil production, is susceptible to quality degradation due to stress-induced incomplete seed degreening, fatty acid oxidation, or poor nutrient accumulation.

Affinity-based capture and identification of protein effectors of the growth regulator ppGpp

open access: yesNature Chemical Biology, 2018
The nucleotide ppGpp is a highly conserved regulatory molecule in bacteria that helps tune growth rate to nutrient availability. Despite decades of study, how ppGpp regulates growth remains poorly understood.

Selective Fluorescent Chemosensor for the Bacterial Alarmone (p)ppGpp

open access: yes, 2016
We have developed the first selective fluorescent chemosensor (PyDPA) for (p)ppGpp, a bacterial and plant alarmone. By using pyrene-excimer fluorescence, PyDPA shows very good selectivity for (p)ppGpp from among other nucleotides in water. PyDPA was used

Distinct roles of ppGpp and DksA in Legionella pneumophila differentiation

open access: yes, 2010
To transit between hosts, intracellular Legionella pneumophila transform into a motile, infectious, transmissive state. Here we exploit the pathogen's life cycle to examine how guanosine tetraphosphate (ppGpp) and DksA cooperate to govern bacterial ...

Identification of novel ppGpp-interaction partners in \(\textit {Escherichia coli}\)

open access: yes, 2023
(p)ppGpp ist ein ubiquitär in Bakterien und Chloroplasten vorkommendes Alarmon. Intrazelluläre Akkumulation des sekundären Botenstoffes vermitteln pleiotrope Anpassungen an Nährstoffmangel durch direkte Interaktion mit Proteinen, wie der RNA Polymerase.

The mediator for stringent control, ppGpp, binds to the β-subunit of Escherichia coli RNA polymerase

open access: yes, 1998
Background Inhibition of transcription of rRNA in Escherichia coli upon amino acid starvation is thought to be due to the binding of ppGpp to RNA polymerase. However, the nature of this interaction still remains obscure.
