Subcellular location

Subcellular Location:
Secreted, extracellular space, extracellular matrix

Function

Function:
May be involved in tissue injury and remodeling. Has significant elastolytic activity. Can accept large and small amino acids at the P1' site, but has a preference for leucine. Aromatic or hydrophobic residues are preferred at the P1 site, with small hydrophobic residues (preferably alanine) occupying P3.
Catalytic Activity:
Hydrolysis of soluble and insoluble elastin. Specific cleavages are also produced at 14-Ala-|-Leu-15 and 16-Tyr-|-Leu-17 in the B chain of insulin.
Cofactor:
COFACTOR: Name=Ca(2+); Xref=ChEBI:CHEBI:29108; ; Note=Binds 4 Ca(2+) ions per subunit.;; COFACTOR: Name=Zn(2+); Xref=ChEBI:CHEBI:29105; ; Note=Binds 2 Zn(2+) ions per subunit.;
