Functional Family Collagenase 3

Enzyme Information

3.4.24.7
Interstitial collagenase.
based on mapping to UniProt P03956
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.
-!- The enzyme takes its name from substrates of the interstitial collagen group - types I, II and III, all of which are cleaved in the helical domain. -!- Alpha-macroglobulins are cleaved much more rapidly. -!- The enzyme is widely distributed in vertebrate animals. -!- Belongs to peptidase family M10B.
