Reaction: Hydrolysis of proteins including elastin, collagen types III and IV, fibronectin and immunoglobulin A, generally with bulky hydrophobic group at P1'. Insulin B chain cleavage pattern identical to that of thermolysin, but specificity differs in other respects
Other names: Pseudomonas elastase; Pseudomonas aeruginosa neutral metalloproteinase
Comment: In peptidase family M4 (thermolysin family). From the pathogenic bacteria Pseudomonas aeruginosa and Legionella pneumophila, and causes tissue damage.
