A comparison of human prothrombin, factor IX (Christmas factor), factor X (Stuart factor), and protein S

Abstract

Human prothrombin, factor IX, and factor X have been idolated in high yield and characterized as the their amino-terminal sequence, molecular weight, amino acid composition, and migration in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. An additional human plasma protein, called protein S, has also been purified and its properties have been compared with those of prothrombin, factor IX, and factor X. Prothrombin (mol wt 72 000), factor IX (mol wt 57 000), and protein S (mol wt 69 000) are single-chain glycoproteins, while factor X (mol wt 59 000) is a glycoprotein composed of two polypeptide chains held together by a disulfide bond(s). The amino-terminal sequence of the light chain of human factor X is homologous with prothrombin, factor IX, and protein S. The heavy chain of human factor X is slightly larger than the heavy chain of bovine factor X and differs from bovine factor X in its amino-terminal sequence.

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.
