Proton/sodium ion antiport in Escherichia coli
Open accessAbstract
In anaerobic suspensions of Escherichia coli, after H+ ions have been translocated outwards across the plasma membrane by a respiratory pulse, re-equilibration is catalysed by Na+. The sudden addition of a Na+ salt causes the effective outward translocation of H+ by an electroneutral process. We conclude that the plasma membrane of E. coli contains a Na+/H+ antiport system that normally translocates Na+ outwards under the influence of an inwardly directed H+-activity gradient.

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.
