Methicillin resistance in Staphylococcus aureus requires glycosylated wall teichoic acids
Open accessAbstract
Staphylococcus aureus peptidoglycan (PG) is densely functionalized with anionic polymers called wall teichoic acids (WTAs). These polymers contain three tailoring modifications: d -alanylation, α- O -GlcNAcylation, and β- O -GlcNAcylation. Here we describe the discovery and biochemical characterization of a unique glycosyltransferase, TarS, that attaches β- O -GlcNAc (β- O - N -acetyl- d -glucosamine) residues to S. aureus WTAs. We report that methicillin resistant S. aureus (MRSA) is sensitized to β-lactams upon tarS deletion. Unlike strains completely lacking WTAs, which are also sensitive to β-lactams, Δ tarS strains have no growth or cell division defects. Because neither α- O -GlcNAc nor β- O -Glucose modifications can confer resistance, the resistance phenotype requires a highly specific chemical modification of the WTA backbone, β- O -GlcNAc residues. These data suggest β- O -GlcNAcylated WTAs scaffold factors required for MRSA resistance. The β- O -GlcNAc transferase identified here, TarS, is a unique target for antimicrobials that sensitize MRSA to β-lactams.

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.
