WebLegend. Settings. Analysis WebInfobox references. (p)ppGpp, guanosine pentaphosphate and tetraphosphate, also known as the "magic spot" nucleotides, [1] are alarmones involved in the stringent response in bacteria that cause the inhibition of RNA synthesis when there is a shortage of amino acids. This inhibition by (p)ppGpp decreases translation in the cell, conserving ...
WebNov 12, 2024 · RelA is a strong ppGpp synthethase but lacks hydrolase activity, whereas SpoT is a weak synthetase but an effective ppGpp hydrolase (Mittenhuber 2001; Atkinson et al. 2011). The SASs and SAHs are found almost exclusively in Gram + bacteria, with most species having one or two SASs (usually named RelP and RelQ) in addition to one … WebIn most bacteria, nutrient limitations provoke the stringent control through the rapid synthesis of the alarmones pppGpp and ppGpp. Little is known about the stringent control in the …
WebDuring starvation, (p)ppGpp accumulates and coordinates diverse transcriptional alterations. (p)ppGpp levels are controlled by two enzymes, RelA and SpoT, which are a monofunctional (p)ppGpp synthetase and a bifunctional (p)ppGpp synthetase/hydrolase, respectively.#Inorganic polyphosphate, a global regulatory molecule, has also been … WebThe heat-induced (p)ppGpp is primarily produced by the ribosome-associated alarmone synthetase Rel, while the small alarmone synthetases RelP and RelQ seem not to be involved. Furthermore, our study shows that the generated (p)ppGpp pulse primarily acts at the level of translation, and only specific genes are regulated at the transcriptional level.
WebShort-term adaptation to changing environments relies on regulatory elements translating changing metabolite concentrations into a specifically optimized transcriptome. So far the focus of analyses has been divided between regulatory elements identified in vivo and kinetic studies of small molecules interacting with the regulatory elements in vitro.
