Structure of Porcine Cholecystokinin‐Pancreozymin: 1. Cleavage with Thrombin and with Trypsin
Abstract
Cholecystokinin‐pancreozymin has been found to have the partial structure Lys (Ala 1, Gly 1, Pro 1, Ser 1) · Arg · Val (Ile 1, Met 1, Ser 1) Lys · Asn (Asx 1, Glx 1, His 1, Leu 2, Pro 1, Ser 2) Arg. Ile (Asp 1, Ser 1) Arg · Asp [Gly 1, Met 2, Trp 1, Tyr (SO 3 H)] Asp · Phe · NH 2. Of the four peptide bonds in this polypeptide, three arginyl and one lysyl, that are cleaved by trypsin only the arginyl‐valine bond is cleaved by thrombin, with retention of the cholecystokinin and pancreozymin activities of the original molecule in the C‐terminal heptacosapeptide. The C‐terminal tryptic octapeptide too has strong cholecystokinin and pancreozymin activity. Except for the replacement of a threonine with methionine the eight amino acid units of this peptide are the same as those that comprise the corresponding part of the molecule of caerulein. Also like that in caerulein, the phenolic group of the only tyrosine of cholecystokinin‐pancreozymin is esterified with sulphuric acid.

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.
