Aplicação
Collagenase from Clostridium histolyticum has been used in determining the degradation rate of collagen biomaterials. It may also be used to determine the enzymatic degradation and enzymatic resistance by the liberated L-leucine measurements.
Collagenase from Clostridium histolyticum, or Clostridiopeptidase A, has been used in a study to assess contact dermatitis with clostridiopeptidase A contained in Noruxol ointment. Clostridiopeptidase A has also been used in a study to investigate the early and successful enzymatıc debridement via collagenase application to pinna in a preterm neonate.
The enzyme has been used in the isolation of mast cells from adult mice. This study generated a large number of connective tissue-type mast cells by the culture of murine fetal skin cells. The product has also been used in the in vitro biodegradation study of Bombyx mori silk fibroin fibers and films, by exposing them to the enzyme for varied time periods.
Ações bioquímicas/fisiológicas
Effective release of cells from tissue requires the action of 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. The pH optimum is 6.3-8.8. The enzyme is typically used to digest the connective components in tissue samples to liberate individual cells. Ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid (EGTA)4; β-mercaptoethanol; glutathione, reduced; thioglycolic acid, sodium; and 2,2′-dipyridyl; 8-hydroxyquinoline are known to inhibit the enzyme activity.
A colagenase é ativada por quatro gramas de átomos de cálcio por mol de enzima. Ela é inibida por ácido etileno glicol-bis(beta-aminoetil éter)-N, N, N′,N′-tetracético, beta-mercaptoetanol, glutationa, ácido tioglicólico e 8-hidroxiquinolina.
Definição da unidade
Uma unidade de digestão de colágeno (CDU) libera peptídeos de colágeno do tendão de Aquiles bovino que equivalem em cor de ninidrina a 1,0 μmol de leucina em 5 horas em pH 7,4 a 37 °C na presença de íons de cálcio. Uma unidade de hidrólise de FALGPA hidrolisa 1,0 μmol de furilacriloil-Leu-Gli-Pro-Ala por min a 25 °C. Uma unidade de protease neutra hidrolisa caseína para produzir cor equivalente a 1,0 μmol de tirosina por 5 h em pH 7,5 a 37 °C. Uma unidade de clostripaína hidrolisa 1,0 μmol de BAEE por min em pH 7,6 a 25 °C na presença de DTT.

Two kinds of layered atelocollagen materials cross-linked with hexamethylene diisocyanate (HMDIC), starch dialdehyde and glyoxal were enzymatically treated by bacterial collagenase. Evaluating collagenase digestion assay for these material showed progressive differences, particularly in the group of samples cross-linked with HMDIC.
