On the Regulation of Guanosine Tetraphosphate Levels in Stringent and Relaxed Strains of Escherichia coli

Abstract

We have examined the intracellular levels of the guanosine tetraphosphate, guanosine 5'-diphosphate 2'- or 3'-diphosphate (ppGpp), in an isogenic pair of stringent and relaxed strains of Escherichia coli. As previously observed, relaxed strains do not accumulate ppGpp during amino acid deprivation, while stringent strains do. However, under all other culture conditions examined, relaxed and stringent cells regulate their ppGpp levels similarly. During carbon deprivation or step-down transitions both strains accumulate ppGpp. Neither strain accumulates appreciable amounts during phosphate deprivation or after treatment with colicin E1. The basal levels of ppGpp observed in both stringent and relaxed strains during balanced growth are, in most cases, the same, and vary inversely with the growth rate and RNA content of the cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
