General description
Elastase, a glycoprotein, is a member of the serine proteases family. It is synthesized by human polymorphonuclear (PMN) leukocytes or by the pancreas. Human granulocyte elastase is liberated in large amounts from granulocytes in chronic inflammatory joint disorders.
Biochem/physiol Actions
Elastase is a catalytic enzyme that catalyzes the cleavage of carboxyl groups on tiny hydrophobic amino acids including glycine, alanine, and valine. Its main function is to break down elastin. Free elastase in some purulent synovial fluids plays a key role in articular cartilage breakdown. Increased elastase levels in the plasma have been seen in patients with evident rheumatoid arthritis.
Elastase(s) can be assayed and differentiated using chromogenic and fluorogenic Pro-Val peptide substrates such as Glp-Pro-Val-pNA and MeOSuc-Ala-Ala-Pro-Val-4-MNA.

Human granulocyte elastase (EC 3.4.21.37) is released from granulocytes in large amounts in chronic inflammatory joint diseases and is therefore of special pathogenic and diagnostic importance. In order to examine the diagnostic significance of this enzyme as a clinico-chemical parameter

Erdosteine is a mucolytic drug whose metabolization gives rise to an active metabolite with an SH group (Met I), which reduces neutrophil release of reactive oxygen species and the peroxynitrite generated by the reaction of superoxide anion with nitric oxide
