Journal ArticleDOI
Separation and quantitation of water soluble cellular metabolites by hydrophilic interaction chromatography-tandem mass spectrometry.
TL;DR: A liquid chromatography-electrospray ionization tandem mass spectrometry (ESI-MS/MS) method for reliable measurement of 141 metabolites, including components of central carbon, amino acid, and nucleotide metabolism is presented.
Journal ArticleDOI
Escherichia coli starvation diets : Essential nutrients weigh in distinctly
TL;DR: Bacterial growth is often limited by availability of nutrients, including carbon, nitrogen, and phosphorus, and the ratios of these elements differ according to the local.
Journal ArticleDOI
RpoS Proteolysis Is Regulated by a Mechanism That Does Not Require the SprE (RssB) Response Regulator Phosphorylation Site
TL;DR: Though phosphorylation contributed to the SprE basal activity, it was found that RpoS proteolysis was still regulated upon carbon starvation, and results indicate thatosphorylation of wild-type SprE occurs by a mechanism that is independent of acetyl phosphate.
Journal ArticleDOI
Decline in ribosomal fidelity contributes to the accumulation and stabilization of the master stress response regulator σS upon carbon starvation
Åsa Fredriksson,Manuel Ballesteros,Celeste N. Peterson,Örjan Persson,Thomas J. Silhavy,Thomas Nyström +5 more
TL;DR: It is suggested that sigma(S) becomes stabilized upon starvation as a result of ClpP sequestration and this sequestration is enhanced by oxidative modifications of aberrant proteins produced by erroneous translation.
Journal ArticleDOI
LrhA Regulates rpoS Translation in Response to the Rcs Phosphorelay System in Escherichia coli
TL;DR: It is shown that LrhA represses RpoS at the level of translation in a manner that is dependent on the small RNA (sRNA) chaperone Hfq, and this mechanism is clarified and insight into the signaling pathways that feed into this regulation is provided.
