The antimicrobial compound reuterin (3-hydroxypropionaldehyde) induces oxidative stress via interaction with thiol groups
Open accessAbstract
Reuterin is an antimicrobial compound produced by Lactobacillus reuteri, and has been proposed to mediate, in part, the probiotic health benefits ascribed to this micro-organism. Despite 20 years of investigation, the mechanism of action by which reuterin exerts its antimicrobial effects has remained elusive. Here we provide evidence that reuterin induces oxidative stress in cells, most likely by modifying thiol groups in proteins and small molecules. Escherichia coli cells subjected to sublethal levels of reuterin expressed a set of genes that overlapped with the set of genes composing the OxyR regulon, which senses and responds to various forms of oxidative stress. E. coli cells mutated for oxyR were more sensitive to reuterin compared with wild-type cells, further supporting a role for reuterin in exerting oxidative stress. The addition of cysteine to E. coli or Clostridium difficile growth media prior to exposure to reuterin suppressed the antimicrobial effect of reuterin on these bacteria. Interestingly, interaction with E. coli stimulated reuterin production or secretion by L. reuteri, indicating that contact with other microbes in the gut increases reuterin output. Thus, reuterin inhibits bacterial growth by modifying thiol groups, which indicates that reuterin negatively affects a large number of cellular targets.

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.
