Abstract

The cyclic AMP (cAMP)-dependent catabolite repression effect in Escherichia coli is among the most intensely studied regulatory processes in biology. However, the physiological function(s) of cAMP signalling and its molecular triggers remain elusive. Here we use a quantitative physiological approach to show that cAMP signalling tightly coordinates the expression of catabolic proteins with biosynthetic and ribosomal proteins, in accordance with the cellular metabolic needs during exponential growth. The expression of carbon catabolic genes increased linearly with decreasing growth rates upon limitation of carbon influx, but decreased linearly with decreasing growth rate upon limitation of nitrogen or sulphur influx. In contrast, the expression of biosynthetic genes showed the opposite linear growth-rate dependence as the catabolic genes. A coarse-grained mathematical model provides a quantitative framework for understanding and predicting gene expression responses to catabolic and anabolic limitations. A scheme of integral feedback control featuring the inhibition of cAMP signalling by metabolic precursors is proposed and validated. These results reveal a key physiological role of cAMP-dependent catabolite repression: to ensure that proteomic resources are spent on distinct metabolic sectors as needed in different nutrient environments. Our findings underscore the power of quantitative physiology in unravelling the underlying functions of complex molecular signalling networks.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Integral control has been implicated in the regulation of nitrogen uptake and in the coordination of nitrogen and carbon utilization.

    “Integral control has been implicated in the regulation of nitrogen uptake (Kim et al, 2012), and the coordination of nitrogen and carbon utilization (You et al, 2013)”
  • Supply-driven activation is used to balance flux among other modular networks such as nitrogen uptake, metabolic regulation of glycolysis, and carbon and nitrogen utilization.

    “Supply-driven activation (and its dynamic counterpart, integral feedforward regulation) is used to balance flux among other modular networks such as nitrogen uptake (Kim et al, 2012), the metabolic regulation of glycolysis (Kochanowski et al, 2012), and carbon and nitrogen utilization (You et al, 2013).”
  • Empirical laws in biology may generally suggest the existence of underlying robust regulatory strategies and pinpoint their molecular implementations, as demonstrated for cAMP signaling.

    “On the contrary, empirical laws in biology may generally suggest the existence of underlying robust regulatory strategies and pinpoint their molecular implementations, as demonstrated recently for the problem of cAMP signaling that has evaded 50 years of genetic and high-throughput studies (You et al, 2013).”
  • Interactions between cell growth and gene expression follow surprisingly simple rules in bacteria.

    “nevertheless, the interactions between cell growth and gene expression follow surprisingly simple rules in bacteria (Scott et al, 2010; You et al, 2013).”

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.
