Biochemistry, 1976 In the course of studies on the metabolic role of diguanosine tetraphosphate during development of Artemia salina, a guanosine monophosphate (GMP) reductase has been found in partially purified from the 150 000g Artemia cysts supernatant. From Lineweaver-Burk plots, two apparent Km values of 5 and 50 muM were obtained for GMP. Xanthosine monophosphate (

From Dormancy to Eradication: Strategies for Controlling Bacterial Persisters in Food Settings
FoodsBacterial persistence, a dormant state that enables microorganisms to survive harsh conditions, is a significant concern in food-industry settings, where traditional antimicrobial treatments often fail to eliminate these resilient cells.

mBio, 2017 Serious bacterial infections in immunocompromised patients require highly effective antibacterial therapy for cure, and thus, this setting may reveal novel mechanisms by which bacteria circumvent antibiotics in the absence of immune pressure.

Guanosine tetraphosphate (ppGpp) is a new player in Brassica napus L. seed development
Food ChemistryRapeseed 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. We hypothesise that the hyperphosphorylated nucleotide alarmone ppGpp (guanosine tetraphosphate), acts as a pivotal regulator of these processes ...

Frontiers in Microbiology, 2019 The alarmone species ppGpp and pppGpp are elementary components of bacterial physiology as they both coordinate the bacterial stress response and serve as fine-tuners of general metabolism during conditions of balanced growth.

Regulation of Escherichia coli aspartate transcarbamylase synthesis by guanosine tetraphosphate and pyrimidine ribonucleoside triphosphates [PDF]
Journal of Bacteriology, 1983 The effects of guanosine tetraphosphate (ppGpp) and pyrimidine ribonucleoside triphosphates on Escherichia coli aspartate transcarbamylase (ATCase) synthesis were examined. To determine the effect of ppGpp, a stringent (relA+) and relaxed (relA) isogenic pair of E. coli K-12 strains was starved for isoleucine, and the residual rate of synthesis of this

mBio, 2019 We have shown that the ligand-responsive MarR family member SlyA plays an important role in transcription activation of multiple virulence genes in Salmonella enterica serovar Typhimurium by responding to guanosine tetraphosphate (ppGpp).

mBio, 2019 The stringent response enables bacteria to respond to a variety of environmental stresses, especially various forms of nutrient limitation. During the stringent response, the cell produces large quantities of the nucleotide alarmone ppGpp, which ...

, 2016 The cyclic di-GMP (c-di-GMP) second messenger represents a signaling system that regulates many bacterial behaviors and is of key importance for driving the lifestyle switch between motile loner cells and biofilm formers.
