RL Submitted (SEP-2023) to UniProtKB.
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; Evidence={ECO:0000256|ARBA:ARBA00036005};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000256|PIRSR:PIRSR621190-2};
CC Note=Can bind about 5 Ca(2+) ions per subunit.
CC {ECO:0000256|PIRSR:PIRSR621190-2};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|PIRSR:PIRSR621190-2};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000256|PIRSR:PIRSR621190-
CC 2};
CC -!- SIMILARITY: Belongs to the peptidase M10A family.
CC {ECO:0000256|ARBA:ARBA00010370}.
