MMP family members share similar fundamental structural characteristics and are classified according to their substrate specificity. By this classification, MMP-9 belongs to the gelatinase subgroup and is known as gelatinase B due to its ability to degrade gelatin. MMP9 is composed of the following domains: 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. The zinc binding motif HEXXHXXGXXH in the catalytic domain, and the “cysteine switch” motif PRCGXPD in the propeptide are common structural signatures, where three histidines in the zinc binding motif coordinate and the cysteine in the propetide coordinate with the catalytic zinc ion. MMP9 is produced by the several cell types, normal alveolar macrophages and granulocytes.
