Interaction between the protein InlB of Listeria monocytogenes and lipoteichoic acid: a novel mechanism of protein association at the surface of Gram‐positive bacteria

Abstract

InlB is a Listeria monocytogenes protein that is sufficient to promote entry in a variety of mammalian cells. The last 232‐amino‐acid domain (Csa) of InlB has been shown to mediate attachment on the listerial surface, although its sequence does not suggest any known mechanism of association to the bacterial surface. InlB is present both on the bacterial surface and in culture supernatants. As has been recently demonstrated, both forms of InlB, soluble and surface‐bound, can trigger signalling in host cells. To elucidate the specific role of each of the two forms, it was important to understand how InlB associates with the bacterial surface. Using microscopy, we find evidence that InlB is partially buried in the cell wall layer, and using fractionation experiments we demonstrate that InlB associates with the bacterial cytoplasmic membrane. Moreover, using purified lipoteichoic acid (LTA) and the three polypeptides InlB, Csa, or InlBΔCsa (InlB lacking the last 232 amino acids), we demonstrate that LTA is a ligand for the Csa domain of InlB. These results provide the first evidence of an interaction between lipoteichoic acids and a bacterial protein involved in adhesion and signalling, and highlight a new mechanism of protein association on the surface of Gram‐positive bacteria.

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.
