The Structure of Ribonuclease-S at 3.5 A Resolution
Open accessAbstract
The electron density map of ribonuclease-S calculated from x-ray diffraction data on the protein and three heavy atom derivatives at 3.5 A resolution is interpretable in terms of main chain and side chain conformation with the aid of pre-existing chemical sequence data and general stereochemical knowledge. Stereoscopic pictures of part of the map and a skeletal model are presented. Features of the structure include 15% helix, 15% hydrophobic core, and appreciable antiparallel-β chain pairing. The configuration of the main chain and assignment of —S—S bridges closely resembles the structure of Rnase-A of Kartha, Bello, and Harker (3) except where there is a chemical difference. The structure is also compatible with much of the relevant chemical literature.

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.
