ABSTRACT
Significant amounts of native collagen can be extracted from bovine articular cartilage after removal of the acid mucopolysaccharides by controlled proteolysis. The fraction thus solubilized upon denaturation gives rise to three identical alpha chains. Cleavage of these chains with CNBr generated nine peptides, all of which contain glycine as one-third of their total amino acid residues. Two of the smaller peptides CB-1 and CB-2 contain partially hydroxylated proline. A similar CNBr digest of intact cartilage also gives a series of peptides identical with those obtained from the soluble cartilage collagen. The absence of cross-linking peptides, the fact that only few beta components are seen in articular cartilage collagen and the similarity in peptide pattern between the two collagen fractions investigated, suggests that this collagen is stabilized by a different cross-linking mechanism, possibly involving an association with the tissue proteoglycans.
