MntR modulates expression of the PerR regulon and superoxide resistance in Staphylococcus aureus through control of manganese uptake
Open accessAbstract
Summary: The Staphylococcus aureus DtxR‐like protein, MntR, controls expression of the mntABC and mntH genes, which encode putative manganese transporters. Mutation of mntABC produced a growth defect in metal‐depleted medium and increased sensitivity to intracellularly generated superoxide radicals. These phenotypes resulted from diminished uptake of manganese and were rescued by the addition of excess Mn(II). Resistance to superoxide was incompletely rescued by Mn(II) for STE035 ( mntA mntH ), and the strain had reduced virulence in a murine abscess model of infection. Expression of mntABC was repressed by Mn(II) in an MntR‐dependent manner, which contrasts with the expression of mntH that was not repressed in elevated Mn(II) and was decreased in an mntR mutant. This demonstrates that MntR acts as a negative and positive regulator of these loci re‐spectively. PerR, the peroxide resistance regulon repressor, acts with MntR to control the expression of mntABC and manganese uptake. The expression of the PerR‐regulated genes, katA (catalase), ftn (ferritin) and fur (ferric uptake regulator), was diminished in STE031 ( mntR ) when grown in excess Mn(II). Therefore, the control of Mn(II)‐regulated members of the PerR regulon and the Fur protein is modulated by MntR through its control of Mn(II) uptake. The co‐ordinated regulation of metal ion homeostasis and oxidative stress resistance via the regulators MntR, PerR and Fur of S. aureus is discussed.

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.
