ENZYME entry: EC

Accepted Name
Alternative Name(s)
Collagenolytic protease.
Reaction catalysed
Hydrolysis of proteins, with broad specificity for peptide bonds. Native collagen is cleaved about 75% of the length of the molecule from the N-terminus. Low activity on small molecule substrates of both trypsin and chymotrypsin
  • From hepatopancreas of the fiddler crab (Uca pugilator).
  • Other serine endopeptidases that degrade collagen, but are not listed separately here, include a second endopeptidase from U.pugilator, digestive enzymes from other decapod crustacea, and an enzyme from the fungus Entomophthora coronata.
  • Belongs to peptidase family S1.
