Matrix metalloproteinases are a family of zinc and calcium-dependent endopeptidases, which degrade extracellular matrix proteins. MMP-9 is secreted as a 92kD zymogen. Cleavage of pro-MMP-9 results in the active enzyme with a molecular weight of ~82kD. MMP-9 has a gelatin-binding domain consisting of three fibronectin type II units, a catalytic domain containing the zinc-binding site, a proline-rich type V collagen-homologous domain and a hemopexin-like domain. MMP9 is produced by monocytes, macrophages, neutrophils, keratinocytes, fibroblasts, osteoclasts and endothelial cells, and is involved in inflammatory responses, tissue remodelling, wound healing, tumor growth and metastasis.
Recombinant protein corresponding to aa113-450 at the catalytic domain of human MMP-9, fused to a N-terminal, 6x His-tag, expressed in E. coli.
