Perkenalan
- Bovine pancreatic deoxyribonuclease (Dnase) is an endonuclease that acts on the phosphodiester bond, particularly those adjacent to pyrimidine nucleosides.
- It produces polynucleotides with a free hydroxyl group at the 3′ end and a phosphate group at the 5′ akhir.
- The optimum pH for DNase activity is 7.8.
- DNase activity is enhanced by divalent metals and inhibited by chelating agents such as EDTA and Sodium dodecyl sulfat (SDS).
- 5 mM calcium ions can serve as stabilizers, protecting DNase from degradation by hydrolases.
- This product is extracted from bovine pancreas and purified using chromatography to remove contamination from other hydrolases.
