Secreted aspartic endopeptidase that allows assimilation of proteinaceous substrates. Can catalyze hydrolysis of the major structural proteins of basement membrane, elastin, collagen, and laminin. Thought to play a significant role in virulence (By similarity). Hydrolysis of proteins with broad specificity. Generally favors hydrophobic residues in P1 and P1', but also accepts Lys in P1, which leads to activation of trypsinogen. Does not clot milk. Belongs to the peptidase A1 family.
