Matrix metalloproteinases (MMPs) are a family of endoproteases that require zinc and calcium for expressing catalytic activity. These enzymes play a central role in the maintenance and remodeling of the extracellular matrix. Elevated expression of their activity, caused either by up-regulation of their expression or down-regulation of their cognate inhibitors, has been implicated in various degenerative disorders, including arthritis, cardiovascular disease, skeletal growth-plate disorders, and cancer metastasis. MMP-3 degrades fibronectin, laminin, collagens III, IV, and X, and cartilage proteoglycans. Recombinant Human MMP-3 is a 42.8 kDa protein containing the entire catalytic N-terminal domain and the C-terminal domain (378 amino acids).

≥ 98% by SDS-PAGE gel and HPLC analyses.
MMP-3 activity was measured by its ability to cleave a chromogenic peptide MMP-3 substrate at room temperature. At an MMP-3 concentration of 2.5 μg/ml, 50% cleavage was achieved at an incubation time of approximately 75 minutes.
