Abstract

Significance: By globally mapping the position of stalled ribosomes in macrolide-treated Staphylococcus aureus , we identified the proteins whose synthesis is affected by this antibiotic. Rather than acting as a nonselective inhibitor, the binding of macrolides to the ribosome tunnel only induces stalling at a few unique sites that are enriched in proline and charged residues. The sequences that flank the stalling sites are highly variable but are essential for efficient stalling. Although it has long been assumed that macrolides inhibit translation after the synthesis of a few residues, we found that stalling could occur at any point during translation. Our results reveal a striking conservation of stalling motifs among all known arrest peptides that strongly suggests a universal ribosome stalling mechanism.

  • Recent studies on NPET binding translation inhibitors like macrolides and Tetracenomycin X have established that the sequence of the nascent peptide plays a crucial role in the binding affinity and efficacy of these inhibitors.

    The section “The Path of the Nascent Peptides Modulates the Stalling Efficiency” (page not supplied) reports that nascent-peptide sequence and path affect macrolide-induced ribosome stalling. It does not establish an effect on inhibitor binding affinity or address Tetracenomycin X. (LLM, conf=0.88)

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.
