Isolation and sequence of the vitamin K-dependent protein from human bone. Undercarboxylation of the first glutamic acid residue.
Open accessAbstract
The gamma-carboxyglutamate-containing protein from human bone has been isolated from proteins released upon demineralization of bone by using a combination of gel filtration and immunoadsorption onto a column of immobilized antibody. The sequence of the protein has been determined by automatic sequence analysis of the whole protein and of peptides isolated from tryptic and Staphylococcus aureus protease digests. The protein consists of 49 amino acids in a single polypeptide chain, contains 2 residues of gamma-carboxyglutamic acid, and a single disulfide bond. There are 4 translational substitutions between the human and calf bone proteins and 23 translational substitutions between the human and swordfish bone proteins. Glu-17 was found to be only 9% gamma-carboxylated, while sequence positions 21 and 24 are fully gamma-carboxylated. The identification of glutamic acid at position 17 represents the first instance where a partially gamma-carboxylated glutamate has been found in a sequence position which is to the NH2-terminal side of a gamma-carboxyglutamate residue. The possible significance of this observation is discussed.

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.
