Abstract

The S100A8/S100A9 heterodimer calprotectin (CP) functions in the host response to pathogens through a mechanism termed “nutritional immunity.” CP binds Mn 2+ and Zn 2+ with high affinity and starves bacteria of these essential nutrients. Combining biophysical, structural, and microbiological analysis, we identified the molecular basis of Mn 2+ sequestration. The asymmetry of the CP heterodimer creates a single Mn 2+ -binding site from six histidine residues, which distinguishes CP from all other Mn 2+ -binding proteins. Analysis of CP mutants with altered metal-binding properties revealed that, despite both Mn 2+ and Zn 2+ being essential metals, maximal growth inhibition of multiple bacterial pathogens requires Mn 2+ sequestration. These data establish the importance of Mn 2+ sequestration in defense against infection, explain the broad-spectrum antimicrobial activity of CP relative to other S100 proteins, and clarify the impact of metal depletion on the innate immune response to infection.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Secreted calprotectin binds to and sequesters Zn, Mn, Ni and Fe in the extracellular milieu through the action of two metal-binding sites termed site I and site II that are formed at the S100A8-S100A9 interface.

    “Secreted calpro­ tectin binds to and sequesters Zn, Mn, Ni and Fe in the extracellular milieu through the action of two metal- binding sites termed site I and site II that are formed at the S100A8-S100A9 interface 20,85,86 .”

    From Nutritional immunity: the battle for nutrient metals at the host–pathogen interface (2022) · cites this paper as [85]

    The section “Two Transition Metal-Binding Sites in CP Are Functionally Inequivalent” (page unavailable) supports Zn and Mn binding at two sites in the S100A8/S100A9 heterodimer, but explicitly reports that calprotectin does not bind iron. The passages found do not establish Ni sequestration. Thus the claim’s four-metal list conflicts with this source. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

  • Calprotectin-mediated manganese restriction causes maximum growth inhibition of bacteria.

    “The central role of manganese starvation for anti-microbial activity has recently been underpinned by the finding that calprotectin-mediated manganese restriction causes maximum growth inhibition of bacteria (246).”

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.
