Abstract

Handling Nitrosative Stress: S-nitrosylation of proteins is a principal mechanism of cellular signaling in eukaryotes but has not been reported in microbes. The transcription factor OxyR serves to protect bacterial cells from reactive oxygen species produced by cell metabolism in the presence of oxygen. Seth et al. (p. 470) found that when cells grew in the presence of nitrate, OxyR was modified by S-nitrosylation of the same cysteine residue that gets oxidized in cells grown aerobically. However, the nitrosylated OxyR activated a different set of genes—some of which appeared to protect the cell from excessive S-nitrosylation.

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

  • Oral bacteria could directly catalyze nitrosation reactions from nitrate without intermediate nitrite formation, as protein S-nitros(yl)ation is an obligate concomitant process of anaerobic respiration on nitrate in E. coli.

    “However, one cannot entirely rule out the possibility that oral bacteria could directly catalyze nitrosation reactions from nitrate without intermediate nitrite formation because recent data show that protein S-nitros(yl)ation is an obligate concomitant process of anaerobic respiration on nitrate in Escherichia coli.43”

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.
