Specific animal collagenases (EC 3.4. 24.3) have been purified by several methods including affinity chromatography on collagen coupled to agarose [l-3] or entrapped in polyacrylamide beads [4]. The occurrence of latent forms of collagenase-or procollagenases-is now well documented [5] but their molecular structure-zymogens or enzyme-inhibitor complexes-and their role in physiology or pathology remain to be elucidated. The present report demonstrates that the procollagenase which is released by mouse bone explants in culture [6] exhibits a striking affinity for native salt-soluble collagen coupled to agarose and that it can be extensively purified (to a specific activity of about 3500 units/mg protein) by affinity chromatography. This efficient, rapid and simple method should have broad applicability in the purification of other mammalian (including human) procollagenases. A preliminary abstracted account of this work has already been presented [7].
