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 42.8kD protein containing the entire catalytic N-terminal domain and the C-terminal domain (378aa).
Source:
Recombinant protein corresponding to human MMP-3, expressed in E.coli.
Biological Activity:
MMP-3 activity was measured by its ability to cleave a chromogenic peptide MMP-3 substrate at room temperature. At a MMP-3 concentration of 2.5ug/ml, 50% cleavage was achieved at an incubation time of ~75 minutes.
Endotoxin:
<0.1ng/ug (1EU/ug)
