Elastases

Supporting information

Elastases are a group of serine proteases that specifically degrade elastin. Elastin, together with collagen, is a key protein that contributes to the mechanical properties of connective tissue.

There are two types of elastases; pancreatic elastase (E.C. 3.4.21.36) and leukocyte elastase (also known as neutrophil elastase) (E.C. 3.4.21.37). Pancreatic elastase is a digestive enzyme secreted from the pancreatic acinar cells and exists in a complex with α1-antitrypsin. Leukocyte elastase is a cytoplasmic enzyme that modifies the function of natural killer cells, monocytes and granulocytes. It specifically cleaves Val-X, Ala-X, Leu-X or Met-X peptide bonds.

Elastases have a physiological role in processes such as neutrophil migration, phagocytosis and tissue remodeling, and are known to contribute to the pathology of pulmonary emphysema, cystic fibrosis, infections, inflammation and atherosclerosis.
