On the Structure of Bovine Pancreatic Ribonuclease B
Open accessAbstract
Ribonuclease B is a constituent of the zymogen granules of bovine pancreatic acinar cells and is secreted in the pancreatic juice of cattle (2). Its isolation from bovine pancreatic juice has been described (3). The enzyme is a glycoprotein that possesses an amino acid composition indistinguishable from that of ribonuclease A and contains carbohydrate to the extent of 6 residues of mannose and 2 residues of glucosamine per molecule. The experiments to be described in the present communication were designed to provide preliminary structural information about the protein and, in particular, to furnish an understanding of the distribution of the carbohydrate in the molecule. The experiments have indicated that the carbohydrate content is accounted for by a single covalently bonded oligosaccharide moiety attached at an aspartic acid or asparagine residue and have provided further presumptive evidence that the structure of the protein is otherwise identical with that of ribonuclease A.

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.
