peptide maps of those collagens from both shark species digested by lysyl endopeptidase are different and are completely different from those of type I collagen from calf skin: calf skin collagen is more susceptible to hydrolysis by lysyl endopeptidase than acid soluble collagen or pepsin soluble collagen from both shark cartilages, possibly due to the higher amount of lysine residues in calf skin collagen
