Accepted name: interstitial collagenase
Reaction: Cleavage of the triple helix of collagen at about three-quarters of the length of the molecule from the N-terminus, at Gly775┼Ile in the α1(I) chain. Cleaves synthetic substrates and α-macroglobulins at bonds where P1′ is a hydrophobic residue
Other name(s): vertebrate collagenase; matrix metalloproteinase 1
Comments: 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. However, α-macroglobulins are cleaved much more rapidly. The enzyme is widely distributed in vertebrate animals. Type example of peptidase family M10
