Protein

Interstitial collagenase

Gene

Mmp1

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Cleaves collagens of types I, II, and III at one site in the helical domain. Also cleaves collagens of types VII and X. May play a role in the deterioration of the heart wall extracellular matrix proteins during the onset of dilated cardiomyopathy.

Catalytic activityi

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.

Cofactori

Protein has several cofactor binding sites:
  • Ca2+By similarityNote: Binds 4 Ca2+ ions per subunit.By similarity
  • Zn2+By similarityNote: Binds 2 Zn2+ ions per subunit.By similarity

Enzyme regulationi

Can be activated without removal of the activation peptide.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
