P81563 - MMP1_RAT


Interstitial collagenase



Rattus norvegicus (Rat)
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli
  1. 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.


    Binds 4 calcium ions per subunit.By similarity
    Binds 2 zinc ions per subunit.By similarity

    Enzyme regulationi

    Can be activated without removal of the activation peptide.
