This enzyme degrades collagen and proteoglycan and can also cause the release of angiotensin II from angiotensin I or angiotensinogen. It has been implicated in connective tissue diseases such as emphysema and rheumatoid arthritis.

Activity: 2-4 units per mg protein. One unit is defined as the amount of enzyme that hydrolyzes one umole of Suc-Ala-Ala Pro-Phe-pNA (1 mM) per minute at 25oC in 160 mM Tris-HCl, pH 7.4, with 1.6 M NaCl.
Purity: >=95% by SDS-PAGE
Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti- HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
