Self-poisoning of Mycobacterium tuberculosis by interrupting siderophore recycling
Open accessAbstract
Significance: Many bacteria acquire iron from the environment by secreting small iron-binding molecules called siderophores. Mycobacterium tuberculosis , the causative agent of tuberculosis, produces the siderophores mycobactin and carboxymycobactin. Here, we demonstrate that M. tuberculosis recycles its siderophores to enable efficient iron use. Disrupting this process causes the intracellular accumulation of deferrated siderophores, which poisons M. tuberculosis. Both externally available and internally synthesized siderophores are toxic for the recycling-deficient mutant, despite its ability to use heme as an iron source. These findings suggest that targeting siderophore recycling may lead to the development of much-needed drugs to combat one of the world’s most deadly bacterial pathogens.

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.
