X-ray structure of human proMMP-1: new insights into procollagenase activation and collagen binding.
Vertebrate collagenases, members of the matrix metalloproteinase (MMP) family, initiate interstitial fibrillar collagen breakdown. It is essential in many biological processes, and unbalanced collagenolysis is associated with diseases such as arthritis, cancer, atherosclerosis, aneurysm, and fibrosis. These metalloproteinases are secreted from the cell as inactive precursors, procollagenases (proMMPs). To gain insights into the structural basis of their activation mechanisms and collagen bind...Expand abstract
