Ligands: INH, ZN Gene: HUMAN STROMELYSIN-1 (Homo sapiens) Activity: Stromelysin 1, with EC number 3.4.24.17 Resources: FirstGlance, OCA, RCSB, PDBsum Disease [MMP3_HUMAN] Defects in MMP3 are the cause of susceptibility to coronary heart disease type 6 (CHDS6) [MIM:614466]. A multifactorial disease characterized by an imbalance between myocardial functional requirements and the capacity of the coronary vessels to supply sufficient blood flow. Decreased capacity of the coronary vessels is often associated with thickening and loss of elasticity of the coronary arteries. Note=A polymorphism in the MMP3 promoter region is associated with the risk of coronary heart disease and myocardial infarction, due to lower MMP3 proteolytic activity and higher extracellular matrix deposition in atherosclerotic lesions. Function [MMP3_HUMAN] Can degrade fibronectin, laminin, gelatins of type I, III, IV, and V; collagens III, IV, X, and IX, and cartilage proteoglycans. Activates procollagenase.

Publication Abstract from PubMed The three-dimensional structure of the catalytic domain of stromelysin-1 complexed with an N-carboxyl alkyl inhibitor has been determined by NMR methods. The global fold consists of three helices, a five stranded beta-sheet and a methionine located in a turn near the catalytic histidines, classifying stromelysin-1 as a metzincin. Stromelysin-1 is unique in having two independent zinc binding sites: a catalytic site and a structural site. The inhibitor binds in an extended conformation. The S1' subsite is a deep hydrophobic pocket, whereas S2' appears shallow and S3' open.
