General annotation (Comments)

Function

Can degrade fibrillar type I, II, and III collagens.

Catalytic activity

Cleavage of interstitial collagens in the triple helical domain. Unlike EC 3.4.24.7, this enzyme cleaves type III collagen more slowly than type I.

Cofactor

Binds 3 calcium ions per subunit By similarity.

Binds 2 zinc ions per subunit By similarity.

Enzyme regulation

Cannot be activated without removal of the activation peptide By similarity.

Subcellular location

Cytoplasmic granule. Secreted › extracellular space › extracellular matrix By similarity. Note: Stored in intracellular granules.

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.
