Chemomechanical Coupling without ATP: The Source of Energy for Motility and Chemotaxis in Bacteria
Open accessAbstract
The source of energy for bacterial motility is the intermediate in oxidative phosphorylation, not ATP directly. For chemotaxis, however, there is an additional requirement, presumably ATP. These conclusions are based on the following findings. ( i ) Unlike their parents, mutants of Escherichia coli and Salmonella typhimurium that are blocked in the conversion of ATP to the intermediate of oxidative phosphorylation failed to swim anaerobically, even when they produced ATP. When respiration was restored to the mutants, motility was simultaneously restored. ( ii ) Carbonylcyanide m -chlorophenylhydrazone, which uncouples oxidative phosphorylation, completely inhibited motility even though ATP remained present. ( iii ) Arsenate did not inhibit motility in the presence of an oxidizable substrate, though it did reduce ATP levels to less than 0.3% ( iv ) Arsenate completely inhibited chemotaxis under conditions where motility was normal.

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.
