General description

Matrix metalloproteinase-12 (MMP-12) is also called as macrophage metalloelastase and is secreted by inflammatory macrophages. It is synthesized as a zymogen and then activated by cleaving the propeptide domain. The MMP-12 gene is localized on chromosome 11.

Biochem/physiol Actions

MMP-12 degrades general matrix components and may have a role in processes such as host defense, cell proliferation, and protein turnover as well as tissue remodeling.
Matrix metalloproteinase-12 (MMP-12) breaks down proteoglycans, collagen type IV and laminin. Its main substrate is elastin.

Unit Definition

One unit equals 100 pmol/min at 37 °C using the colorimetric thiopeptolide Ac-Pro-Leu-Gly-S-Leu-Leu-Gly-OEt as substrate.

Physical form

Solution in 50 mM Tris, 5 mM calcium chloride, 500 mM sodium chloride, 20 μM zinc chloride, 0.5% Brij® L23, and 30% glycerol, pH 9.5.
