Collagenase is activated by four gram atom calcium per mole enzyme. It is inhibited by ethylene glycol-bis(beta-aminoethyl ether) - N, N, N′,N′-tetraacetic acid, beta-mercaptoethanol, glutathione, thioglycolic acid and 8-hydroxyquinoline.

应用
Collagenase from Clostridium histolyticum has been used in a study to investigate the degradation of collagen by the cariogenic bacteria, Streptococcus mutans. Collagenase from Clostridium histolyticum has also been used in a study to investigate the survivability of collagen micronetworks in the presence of collagenase.

Collagenase has been used in the preparation of arterial tissue for the study of Advanced Glycosylation End Products (AGE). The enzyme has also been used along with other proteases for the disaggregation of human tumor, mouse kidney, human brain, and lung epithelial tissues among several others. It is also effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes. The product has been used to digest forearm skin biopsies from Parkinson disease patients to grow human skin fibroblast primary cultures. The enzyme from Sigma has been used for rodent islet isolation in a study that assayed glucokinase functions.
