Application

Collagenase from Clostridium histolyticum, or Clostridiopeptidase A, has been used in a study to assess the synthesis and in vitro evaluation of macromolecular antitumour derivatives based on phenylenediamine mustard. Clostridiopeptidase A has also been used in a study to investigate the enzymatic debridement of burn wounds with collagenase.

Biochem/physiol Actions

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.
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.

Unit Definition

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.

Seventy-eight pediatric burn patients treated by enzymatic debridement with collagenase clostridiopeptidase A (CCA), were compared to 41 patients those burn wounds were excised surgically. Patients whose burn wounds were initially assessed as partial-thickness at admission were enrolled in the study.

Poly-[N-(2-hydroxyethyl)-L-glutamine] (PHEG) and poly(ethylene glycol) (PEG)-grafted PHEG conjugates of N,N-di(2-chloroethyl)-4-phenylenediamine mustard (PDM) were synthetised. A collagenase-sensitive oligopeptide spacer was selected to link the cytotoxic agent PDM onto the polymeric carrier. First, the oligopeptide-drug conjugate, L-pro-L-leu-gly-L-pro-gly-PDM, was prepared. In a second

Protocolos

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.
