Abstract

We describe the crystal structure of the complete Thermus thermophilus 70 S ribosome containing bound messenger RNA and transfer RNAs (tRNAs) at 5.5 angstrom resolution. All of the 16 S , 23 S , and 5 S ribosomal RNA (rRNA) chains, the A-, P-, and E-site tRNAs, and most of the ribosomal proteins can be fitted to the electron density map. The core of the interface between the 30 S small subunit and the 50 S large subunit, where the tRNA substrates are bound, is dominated by RNA, with proteins located mainly at the periphery, consistent with ribosomal function being based on rRNA. In each of the three tRNA binding sites, the ribosome contacts all of the major elements of tRNA, providing an explanation for the conservation of tRNA structure. The tRNAs are closely juxtaposed with the intersubunit bridges, in a way that suggests coupling of the 20 to 50 angstrom movements associated with tRNA translocation with intersubunit movement.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The RNA World theory's plausibility is bolstered by experimental findings including centrality of RNA nucleotides in metabolism, nature of the ribosome, and abiotic synthesis of RNA nucleosides.

    “The plausibility of this theory is bolstered by several experimental findings, including the centrality of RNA nucleotides in metabolism, the nature of the ribosome (a ribozyme) (Ban et al. 2000; Wimberly et al. 2000; Yusupov et al. 2001), and the abiotic synthesis of RNA nucleosides (Powner et al. 2009).”
  • The catalytic core of the ribosome comprises RNA.

    “The finding that the catalytic core of the ribosome comprises RNA lent considerable credence to the RNA world theory (4–6).”

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.
