Pseudolysin (EC 3.4.24.26, Pseudomonas elastase, Pseudomonas aeruginosa neutral metalloproteinase) is an enzyme.^[1]^[2]^[3]^[4]^[5] This enzyme catalyses the following chemical 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

This enzyme belongs to the peptidase family M4 (thermolysin family).
