FIDDLER CRAB COLLAGENASE COMPLEXED TO ECOTIN

Released:

Function and Biology Details

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.
