The enzyme is supplied as a mixture of the zymogen and active enzyme in:Preservative: 0.01% Sodium AzideConstituents: 50% Glycerol, 0.025% Brij 35, 5mM Calcium chloride, 250mM Sodium chloride, 25mM Tris, pH 7.4
Matrix metalloproteinase 3
Can degrade fibronectin, laminin, gelatins of type I, III, IV, and V; collagens III, IV, X, and IX, and cartilage proteoglycans. Activates procollagenase.
Belongs to the peptidase M10A family. Contains 4 hemopexin-like domains.
The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.
