Localisation of the prosthetic sugar groups of bovine colostrum kappa-casein.
The study of glycopeptides obtained after enzymic digestions of bovine colostrum kappa-caseinoglycopeptide obtained 15 minutes after calving, demonstrated the presence of two prosthetic sugar groups linked to threonine residues, instead of only one and up to 10 in the case of bovine (normal) and human caseinoglycopeptides, respectively. The secondary structure of bovine kappa-caseinoglycopeptide was reinvestigated.
