We investigated in vitro the ability of cathepsin B, a lysosomal cysteine proteinases, to generate multiple molecular forms of pyridinoline crosslinks from insoluble bone type I collagen, and we studied the effects of various concentrations of divalent ions such as calcium (Ca2+) and magnesium (Mg2+) on this process. Our results have shown that the addition of either Ca2+ or Mg2+ greatly enhanced the release of pyridinoline crosslinks, the greatest effects being obtained at 50-75 mM. By dialysis and gel filtration chromatography methods, we attempted to separate the different molecular species of peptides containing pyridinoline crosslinks resulting from the digestion of bone with catepsin B. In a Ca2+ and Mg2+ free buffer, the molecular we...
