ELANE protease
Chromatographically purified from leucocytes of purulent human sputum and lyophilized. The lyophilized, salt-free, soluble powder is stable for over a year when stored at 5 C. The protein is greater than 95percent pure by SDS-PAGE and is free of cathepsin G, MPO and lysozyme. 800-900 units per mg of protein on the substrate Suc-Ala-Ala-Ala-pNA. 15000-19000 units per mg protein on the substrate MeO-Suc-Ala-Ala-Pro-Val-pNA. One unit will hydrolyze 1 nanomole of substrate per minute at pH 7.5 and 25 C. The following diluents and concentrations are recommended: 1) 1 mg/ml in 0.05 M Na Acetate pH 5.0 containing 0.1 M NaCl. Stable 7 days at 5 C (in ice). 2) 10 mg/ml in 50percent glycerol 50percent 0.02 M Na Acetate pH 5. Stable at least 60 days at -20 C with 20 cycles between -20 C and 5 C. 3) May be dissolved at 10 mg/ml in 2 mM HoAc and re-lyophilized in smaller quantities. Stability is better in acidic (pH 5.0) than basic buffers. Inactivation may occur at pH 8.0 due to autolysis and/or proteolysis by trypsin such as bovine pancreatic trypsin. Proteolysis can be inhibited by benzamidine. Autolysis and proteolysis can be inhibited by elastatinal. However, elastatinal is also an inhibitor of elastase. Low pH protects the elastase from both autolysis and proteolysis.

NCBI Summary for ELANE
Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Humans have six elastase genes which encode the structurally similar proteins. The product of this gene hydrolyzes proteins within specialized neutrophil lysosomes, called azurophil granules, as well as proteins of the extracellular matrix following the protein's release from activated neutrophils. The enzyme may play a role in degenerative and inflammatory diseases by its proteolysis of collagen-IV and elastin of the extracellular matrix. This protein degrades the outer membrane protein A (OmpA) of E. coli as well as the virulence factors of such bacteria as Shigella, Salmonella and Yersinia. Mutations in this gene are associated with cyclic neutropenia and severe congenital neutropenia (SCN). This gene is clustered with other serine protease gene family members, azurocidin 1 and proteinase 3 genes, at chromosome 19pter. All 3 genes are expressed coordinately and their protein products are packaged together into azurophil granules during neutrophil differentiation. [provided by RefSeq, May 2009]
UniProt Comments for ELANE
ELANE: Modifies the functions of natural killer cells, monocytes and granulocytes. Inhibits C5a-dependent neutrophil enzyme release and chemotaxis. Defects in ELANE are a cause of cyclic haematopoiesis (CH); also known as cyclic neutropenia. CH is an autosomal dominant disease in which blood-cell production from the bone marrow oscillates with 21-day periodicity. Circulating neutrophils vary between almost normal numbers and zero. During intervals of neutropenia, affected individuals are at risk for opportunistic infection. Monocytes, platelets, lymphocytes and reticulocytes also cycle with the same frequency. Defects in ELANE are the cause of neutropenia severe congenital autosomal dominant type 1 (SCN1). SCN1 is a disorder of hematopoiesis characterized by a maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections. Belongs to the peptidase S1 family. Elastase subfamily.
