Activity Regulation ACTIVITY REGULATION: Completely inhibited by metalloprotease inhibitors EDTA, 1,10-phenanthroline, and phosphoramidon, but not by inhibitors specific for serine, cysteine, and aspartate proteases, such as PMSF, antipain, leupeptin, chymostatin, and pepstatin. Zn(2+) and, to a lesser extent, Co(2+) reversed the inhibition of 1,10-phenanthroline. {ECO:0000269|PubMed:8188335}.

EC Number 3.4.24.-
Enzyme Function FUNCTION: Secreted metalloproteinase that allows assimilation of proteinaceous substrates and probably acts as a virulence factor (By similarity). Catalyzes the hydrolysis of elastin (PubMed:7927676, PubMed:8188335). Hydrolyzes azocasein, synthetic fluorigenic substrate Abz-Ala-Ala-Phe-Phe-pNA, and His-Leu, Ala-Leu, Tyr-Leu, Gly-Phe, and Phe-Phe peptide bonds in the B chain of insulin (PubMed:8188335). {ECO:0000250, ECO:0000269|PubMed:7927676, ECO:0000269|PubMed:8188335}.
Temperature Dependency BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 60 degrees Celsius against azocasein. Retains 50% of the activity by incubation at 60 degrees Celsius for 1 hour. {ECO:0000269|PubMed:8188335};
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 7.5-8.0. {ECO:0000269|PubMed:8188335};
