General annotation (Comments)

Catalytic activity

Cleavage of the triple helix of collagen at about three-quarters of the length of the molecule from the N-terminus, at 775-Gly-|-Ile-776 in the alpha-1(I) chain. Cleaves synthetic substrates and alpha-macroglobulins at bonds where P1' is a hydrophobic residue.

Cofactor

Binds 4 calcium ions per subunit By similarity.

Binds 2 zinc ions per subunit By similarity.

Enzyme regulation

Can be activated without removal of the activation peptide By similarity.

Subcellular location

Secretedextracellular spaceextracellular matrix Probable.

Domain

The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

Sequence similarities

Belongs to the peptidase M10A family.

Contains 4 hemopexin-like domains.
