CC   -!- FUNCTION: This enzyme is a serine protease capable of degrading the
CC       native triple helix of collagen.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of proteins, with broad specificity for peptide
CC         bonds. Native collagen is cleaved about 75% of the length of the
CC         molecule from the N-terminus. Low activity on small molecule
CC         substrates of both trypsin and chymotrypsin.; EC=3.4.21.32;
CC   -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00274}.
