Cyanogen bromide fragments of bovine cervical mucus glycoprotein.
Treatment of bovine cervical mucus glycoprotein with cyanogen bromide gives four fractions, with the molecular weights of the three major fractions being 230 000, 130 000, and 35 000. The results indicate that, as for other glycoproteins, there are different regions along the protein core, some of which have a high sugar content and others which contain considerably less carbohydrate; it seems likely that the regions of lower sugar content may be important to intermolecular linkages. The data suggest that the basic unit of the glycoprotein has a molecular weight of 550 000-600 000, with its protein core consisting of approx. 1200 amino acid residues.
