Abstract

Genetic information encoded in messenger RNA is translated into protein by the ribosome, which is a large nucleoprotein complex comprising two subunits, denoted 30S and 50S in bacteria. Here we report the crystal structure of the 30S subunit from Thermus thermophilus, refined to 3 A resolution. The final atomic model rationalizes over four decades of biochemical data on the ribosome, and provides a wealth of information about RNA and protein structure, protein-RNA interactions and ribosome assembly. It is also a structural basis for analysis of the functions of the 30S subunit, such as decoding, and for understanding the action of antibiotics. The structure will facilitate the interpretation in molecular terms of lower resolution structural data on several functional states of the ribosome from electron microscopy and crystallography.

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).”
  • These changes could be mediated by S12, which is in close proximity to the top of h44 and also appears to interact with Tet(O).

    “These changes could be mediated by S12, which is in close proximity to the top of h44 (43, 58) and also appears to interact with Tet(O) (45).”

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.
