Protein attributes
| Sequence length | 469 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Function | Cleaves collagens of types I, II, and III at one site in the helical domain. Also cleaves collagens of types VII and X. |
| 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. |
| Subcellular location | Secreted › extracellular space › extracellular matrix By similarity. |
| 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. |
