Deoxyribonuclease
Source: Bovine Pancrease
General description
Bovine pancreatic deoxyribonuclease (DNase) is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with free hydroxyl group at the 3' position and phosphate group at the 5' position. The optimum pH is 7.8. DNase I is activated by bivalent metals, and inhibited by chelating agents such EDTA and sodium dodecyl sulfate. DNase I can be stabilized against proteolytic digestion by 5 mM Ca2+
