CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cleavage of the triple helix of collagen at about three-
CC quarters of the length of the molecule from the N-terminus, at 775-
CC Gly-|-Ile-776 in the alpha1(I) chain. Cleaves synthetic substrates
CC and alpha-macroglobulins at bonds where P1' is a hydrophobic
CC residue.; EC=3.4.24.7;
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC Note=Binds 4 Ca(2+) ions per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Can be activated without removal of the activation
CC peptide. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000305}.
CC -!- DOMAIN: The conserved cysteine present in the cysteine-switch motif
CC binds the catalytic zinc ion, thus inhibiting the enzyme. The
CC dissociation of the cysteine from the zinc ion upon the activation-
CC peptide release activates the enzyme.
CC -!- SIMILARITY: Belongs to the peptidase M10A family. {ECO:0000305}.
