RSH enzyme diversity for (p)ppGpp metabolism in Phaeodactylum tricornutum and other diatoms

, 2019
International audiencethe nucleotides guanosine tetraphosphate and pentaphosphate (together known as (p)ppGpp or magic spot) are produced in plant plastids from GDp/Gtp and Atp by RelA-Spot homologue (RSH) enzymes. in the model plant Arabidopsis (p)ppGpp

Golden magic: RSH enzymes for (p)ppGpp metabolism in the diatom $Phaeodactylum$ $tricornutum$

, 2018
The nucleotides guanosine tetraphosphate and pentaphosphate (together known as (p)ppGpp or magic spot) are produced in plant plastids from GDP/GTP and ATP by RelA-SpoT homologue (RSH) enzymes. In the model plant Arabidopsis (p)ppGpp regulates chloroplast

Effects of Manganese on (p)ppGpp Homeostasis in Bacillus subtilis

, 2018
The bacterial nucleotide signal (p )ppGpp is an important signal for stress survival, antibiotic tolerance, and virulence in common pathogens. In addition, the group 7 metal manganese has been implicated in having critical roles in proper cell function

The Physiological Significance of (p)ppGpp in Enterococcus faecalis

Thesis (Ph.D.)--University of Rochester. School of Medicine & Dentistry. Dept. of Microbiology, Immunology and Virology, 2014.The stringent response (SR) is a conserved stress response in bacteria that shifts cells from a growth mode to a survival mode.

(p)ppGpp, a Small Nucleotide Regulator, Directs the Metabolic Fate of Glucose in Vibrio cholerae

, 2015
When V. cholerae encounters nutritional stress, it activates (p)ppGpp-mediated stringent response. The genes relA and relV are involved in the production of (p)ppGpp, whereas the spoT gene encodes an enzyme that hydrolyzes it.

(p)ppGpp regulates type 1 fimbriation of Escherichia coli by modulating the expression of the site-specific recombinase FimB

, 2006
In this report we have examined the role of the regulatory alarmone (p)ppGpp on expression of virulence determinants of uropathogenic Escherichia coli strains. The ability to form biofilms is shown to be markedly diminished in (p)ppGpp-deficient strains.
