MomL inhibits bacterial antibiotic resistance through the starvation stringent response pathway [PDF]

open access: yesmLife, 2022
Antibiotic resistance in gram‐negative pathogens has become one of the most serious global public health threats. The role of the N‐acyl homoserine lactone (AHL)‐mediated signaling pathway, which is widespread in gram‐negative bacteria, in the bacterial ...

The Stringent Response-Regulated sRNA Transcriptome of Borrelia burgdorferi [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
The Lyme disease spirochete Borrelia (Borreliella) burgdorferi must tolerate nutrient stress to persist in the tick phase of its enzootic life cycle. We previously found that the stringent response mediated by RelBbu globally regulates gene expression to

The Impact of the Stringent Response on TRAFAC GTPases and Prokaryotic Ribosome Assembly [PDF]

open access: yesCells, 2019
Many facets of ribosome biogenesis and function, including ribosomal RNA (rRNA) transcription, 70S assembly and protein translation, are negatively impacted upon induction of a nutrient stress-sensing signalling pathway termed the stringent response ...

Role of the Extracytoplasmic Function Sigma Factor SigE in the Stringent Response of <i>Mycobacterium tuberculosis</i>. [PDF]

open access: yesMicrobiol Spectr, 2023
Bacteria respond to nutrient starvation implementing the stringent response, a stress signaling system resulting in metabolic remodeling leading to decreased growth rate and energy requirements.

The transcription factor DksA exerts opposing effects on cell division depending on the presence of ppGpp

open access: yesmBio, 2023
Bacterial cell size is a multifactorial trait that is influenced by variables including nutritional availability and the timing of cell division. Prior work revealed a negative correlation between concentration of the alarmone (p)ppGpp (ppGpp) and cell ...

(p)ppGpp and c-di-AMP Homeostasis Is Controlled by CbpB in Listeria monocytogenes

open access: yesmBio, 2020
The facultative intracellular pathogen Listeria monocytogenes, like many related Firmicutes, uses the nucleotide second messenger cyclic di-AMP (c-di-AMP) to adapt to changes in nutrient availability, osmotic stress, and the presence of cell wall-acting ...

Tolerance and Persistence to Drugs: A Main Challenge in the Fight Against Mycobacterium tuberculosis

open access: yesFrontiers in Microbiology, 2020
The treatment of tuberculosis is extremely long. One of the reasons why Mycobacterium tuberculosis elimination from the organism takes so long is that in particular environmental conditions it can become tolerant to drugs and/or develop persisters able ...

Clinical rel mutations in Staphylococcus aureus prime pathogen expansion under nutrient stress

open access: yesmSphere, 2023
Persistent infection by Staphylococcus aureus has been linked to the bacterial stringent response (SR), a conserved stress response pathway regulated by the Rel protein.

Classic Spotlight: Studies of the Stringent Response [PDF]

open access: yesJournal of Bacteriology, 2016
The views expressed in this Editorial do not necessarily reflect the views of the journal or of ASM. Early investigators of bacterial metabolism felt that the major activities of the cell must be balanced so that every component of the cell could be duplicated in the same time interval.

Quantitative Physiology and Proteome Adaptations of Bifidobacterium breve NRBB57 at Near-Zero Growth Rates

open access: yesMicrobiology Spectrum, 2023
In natural environments, nutrients are usually scarce, causing microorganisms to grow slowly while staying metabolically active. These natural conditions can be simulated using retentostat cultivations.
