Abstract

Two-component systems (TCS) comprising sensor histidine kinases and response regulator proteins are among the most important players in bacterial and archaeal signal transduction and also occur in reduced numbers in some eukaryotic organisms. Given their importance to cellular survival, virulence, and cellular development, these systems are among the most scrutinized bacterial proteins. In the recent years, a flurry of bioinformatics, genetic, biochemical, and structural studies have provided detailed insights into many molecular mechanisms that underlie the detection of signals and the generation of the appropriate response by TCS. Importantly, it has become clear that there is significant diversity in the mechanisms employed by individual systems. This review discusses the current knowledge on common themes and divergences from the paradigm of TCS signaling. An emphasis is on the information gained by a flurry of recent structural and bioinformatics studies.

  • Typically, lemA is part of a two-component regulatory system, which are involved in regulation of various cellular processes varying from phosphate uptake, to respiration, to sporulation.

    “Typically, lemA is part of a two-component regulatory system, which have been well-studied across bacterial systems92−94 (but that have not yet been observed in Mycoplasma to our knowledge), and are involved in regulation of various cellular processes varying from phosphate uptake, to respiration, to sporulation.”

    From Toward the Complete Functional Characterization of a Minimal Bacterial Proteome (2022) · cites this paper as [92]

    The Introduction describes two-component systems as widespread in bacteria, and the Signal Detection and Transmission section links one such system to nitrate/nitrite respiration. The Response Generation section identifies a sporulation pathway. Our copy does not identify LemA as a component of such a system or establish phosphate uptake as one of the regulated processes; it discusses a phosphate-limitation response instead. No page numbers were provided for these passages. (LLM, conf=0.85)

  • Gene /0604 is lemA-gacS, a two component sensor/membrane protein involved in cell growth and morphology.

    “lemA-gacS/0604 | cell growth and morphology | two component sensor/membrane”

    From Toward the Complete Functional Characterization of a Minimal Bacterial Proteome (2022) · cites this paper as [92]

    The Signal Detection and Transmission section (Transmembrane helical segments; page unavailable) describes transmembrane sensor kinases, supporting the general protein-category description. It does not identify lemA-gacS as gene /0604 or establish its involvement in cell growth and morphology; searches for those terms found no such passage. (LLM, conf=0.78)

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.
