Estado viável não cultivável em Salmonella enterica sorovar Enteritidis deficiente na síntese de (p)ppGpp
… adversas. S. enterica é capaz de produzir (p)ppGpp, um nucleotídeo responsável pelo controle da expressão gênica no nível da transcrição e da tradução, em condições de estresse nutricional. Em razão da expressão gênica determinada pelo acúmulo de (p)ppGpp, S. enterica suporta condições …

Relative contributions of the stringent response mediators (p)ppGpp and DksA to Haemophilus ducreyi virulence in humans
… by guanosine tetra- and pentaphosphate [(p)ppGpp] and the transcriptional regulator DksA. (p)ppGpp and DksA jointly interact with RNA polymerase to regulate genes critical for bacterial survival. We hypothesized that the stringent response is required for H. ducreyi virulence in humans. A …

In search for the inhibitors of Escherichia coli stringent response factor RelA
… mis aktiveeritakse sõltuvalt alarmoonmolekuli (p)ppGpp rakusisesest kontsentratsioonist. (p)ppGpp on võimeline reguleerima mitmete ensüümide aktiivsust, kuid peamiseks märklauaks on RNA polümeraas. (p)ppGpp rakusisest taset kontrollivad E. coli RelA-SpoT-ga homoloogsed valgud (RSH), mis kas …

Transcription in Mycoplasma pneumoniae
… der Rolle von RelA und des Signalmoleküls (p)ppGpp in M. pneumoniae wurden durchgeführt. Während gezeigt werden konnte, dass die Mechanismen, die zur RelA-abhängigen Synthese von (p)ppGpp in diesem Organismus konserviert sind, konnte, abgesehen von der Unfähigkeit (p)ppGpp herzustellen kein …

Random walks in the stringent response
… aminohappenäljale sünteesib signaalmolekuli (p)ppGpp. See signaalmolekul mõjutab transkriptsiooni, translatsiooni ja rakkude jagunemist. Meie töötasime välja ühe molekuli jälgimise mikroskoopia metoodika, mis võimaldab mõõta molekulide difusiooni rakus. Kasutasime seda metoodikat erineva …

Characterization of beneficial mutations in unsaturated fatty acid biosynthesis that are recurrent dead-ends in a long-term evolution experiment with Escherichia coli
… SpoT to produce the cellular "alarmone" (p)ppGpp, inhibiting cell growth during the stringent response. Thus, it is possible that fabR mutations that prolong fatty acid synthesis and spoT mutations that alter the production of (p)ppGpp may both benefit cells by affecting the stringent …

Mathematical Model of the Cell Cycle Control and Asymmetry Development in Caulobacter crescentus
… and guanosine pentaphosphate or tetraphosphate (pppGpp or ppGpp), under normal and stressful conditions. This research suggests that the RelA-SpoT homolog enzymes have the potential to effectively influence the cell cycle in response to nutrition changes by regulating cdG and (p)ppGpp levels. We …
