Organism

Homo sapiens (Human) [Complete proteome]

Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	467 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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. Binds 2 zinc ions per subunit.
Enzyme regulation	Cannot be activated without removal of the activation peptide.
Subcellular location	Cytoplasmic granule. Secreted › extracellular space › extracellular matrix Probable. Note: Stored in intracellular granules.
Tissue specificity	Neutrophils.
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.
