Descripción

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.

Biochem/physiol Actions

La colagenasa es activada por cuatro átomo-gramos de calcio por mol de enzima. Es inhibida por el ácido etilenglicol-bis(beta-aminoetil éter) - N, N, N′,N′-tetraacético, el beta-mercaptoetanol, el glutatión, el ácido tioglicólico y la 8-hidroxiquinolina.

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.

Preparation Note

Prepared from Type V (C9263)

Analysis Note

Also contains clostripain, nonspecific neutral protease, and tryptic activities.

Other Notes

Una unidad de digestión de colágeno (CDU) libera péptidos del colágeno del tendón de Aquiles bovino que equivalen en la reacción de color de la ninhidrina a 1,0 μmoles de leucina en 5 horas a pH 7,4 y 37 °C en presencia de iones calcio. Una unidad de hidrólisis FALGPA hidroliza 1,0 μmoles de furilacriloil-Leu-Gly-Pro-Ala por minuto a 25°C. Una unidad de proteasa neutra hidroliza la caseína para producir color equivalente a 1,0 μmoles de tirosina por 5 horas a pH 7,5 y 37°C. Una unidad de clostripaína hidroliza 1,0 μmoles de BAEE por minuto a pH 7,6 y 25°C en presencia de DTT.
