Application

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, lung epithelium and many other tissues. It is also effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes.
Collagenase from Clostridium histolyticum has been used:
  • to induce intracerebral hemorrhage (ICH) in mice
  • to digest collagen 3D gels for immunofluorescence
  • to cause focal blood extravasation and hemorrhage in mouse

Biochem/physiol Actions

La collagénase est activée à l′aide de quatre atome-grammes de calcium par mole d′enzyme. Elle est inhibée par l′acide éthylèneglycol-bis(bêta-aminoéthyléther)-N,N,N′,N′-tétraacétique, le bêta-mercaptoéthanol, le glutathion, l′acide thioglycolique et la 8-hydroxyquinoline.
Effective release of cells from tissue requires the action of both collagenase enzymes and the neutral protease. Collagenase is activated by four gram atom calcium (Ca2+) per mole enzyme. The culture filtrate is thought to contain at least 7 different proteases ranging in molecular weight from 68-130 kDa (pH optimum: 6.3-8.8). The enzyme recognizes the sequence -R-Pro-8-X-Gly-Pro-R-, where X is most often a neutral amino acid.
Clostridium histolyticum contains two classes of collagenases. Clostridial collagenases are more effective than mammalian collagenases. It cleaves at multiple cleavage sites within the collagen triple helix. Clostridial collagenases are involved in bacterial invasion in gas gangrene.

Preparation Note

Prepared from Type VII (C0773). A stock solution may be prepared by dissolving 0.05-0.1 mg of collagenase in one mL of 50 mM TES buffer containing 0.36 mM calcium chloride (TESCA), pH 7.4 at 37 °C.

Other Notes

Une unité de digestion de collagène (UDC) libère une quantité de peptides à partir du collagène d′un tendon d′Achille de bovin équivalant, en termes de couleur avec la méthode à la ninhydrine, à 1,0 μmole de leucine en 5 heures à pH 7,4 et à 37 °C en présence d′ions calcium. Une unité d′hydrolyse de FALGPA hydrolyse 1,0 μmole de furylacryloyl-Leu-Gly-Pro-Ala par minute à 25 °C. Une unité de protéase neutre hydrolyse la caséine et produit une couleur équivalente à 1,0 μmole de tyrosine en 5 heures à pH 7,5 et à 37 °C. Une unité de clostripaïne hydrolyse 1,0 μmole de BAEE par minute à pH 7,6 et à 25 °C en présence de DTT.

Protocoles

To measure collagenase activity, N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala is used in a continuous spectrophotometric rate determination at 345 nm. Collagenase hydrolyzes collagen peptide bonds.

Intracerebral hemorrhage (ICH) refers to bleeding in the brain and is associated with the release of large amount of inflammasomes, and the activation of different cell death pathways. These cell death pathways lead to removal of inactivated and damaged cells
