Characterization of Deoxyribonucleases

چکیده
Increases in deoxyribonuclease activity assayed at alkaline pH can be observed in poxvirus-infected cells when native or denatured deoxyribonucleic acid (DNA) is used as substrate. The deoxyribonuclease assayable with native DNA as substrate, induced in HeLa cells by cowpoxvirus or vaccinia virus WR, can be separated from the corresponding enzyme present in normal cells by chromatography on diethylaminoethyl cellulose. In addition, the two enzymes induced in the virusinfected cells differ from each other in their chromatographic properties. The two induced enzymes have been further characterized with respect to properties of enzymatic reaction.

Characterization of a nuclease produced by Staphylococcus aureus.
The conformational parameters of a nuclease produced by growing cultures of Staphylococcus aureus have been determined. This nuclease exhibits both ribonuclease and deoxyribonuclease activities. It has been shown to have a pH optimum of 9.2 and an absolute requirement for calcium ions. The experimental data are compatible with a compact globular protein of mol wt 17,000 and with a helical conte...
متن کاملCharacterization of different deoxyribonucleases in human lymphocytes.
Four groups of deoxyribonuclease activities from human lymphocytes have been characterized by deoxyribonuclease assay in DNA-containing polyacrylamide gels following their separation by disc-electrophoresis. All activities hydrolyse DNA endonucleolytically. One neutral deoxyribonuclease found in the cytoplasmic fraction prefers native or UV-irradiated DNA over denatured DNA as substrate and is ...
