Characterization of a camel milk protein rich in proline identifies a new beta-casein fragment.
A camel milk whey protein has been isolated by reverse-phase high performance liquid chromatography. The protein is, like caseins, rich in proline (25% of the whole protein). The N-terminal amino acid sequence shows that the protein is homologous with a C-terminal region of beta-caseins analyzed from other species. The protein is concluded to be a fragment of beta-casein, derived from a non-tryptic type of cleavage of the parent molecule, and increasing the multiplicity of known casein products.
