An ATPase activity that is completely dependent on DNA is associated with the ATP-dependent DNase (recB-recC enzyme) purified from Escherichia coli. There is a strong correlation between the ATPase and the DNase activities under various assay conditions. With E. coli DNA as substrate, 8-9 molecules of ATP are hydrolyzed to ADP and inorganic phosphate for every phosphodiester bond hydrolyzed by the DNase. The possible functional relationship of the ATPase and DNase activities is discussed.
一种完全依赖于DNA的ATP酶活性与从大肠杆菌中纯化得到的依赖ATP的DNA酶(recB-recC酶)相关。在各种测定条件下,ATP酶活性和DNA酶活性之间存在很强的相关性。以大肠杆菌DNA为底物时,DNA酶每水解一个磷酸二酯键,就有8 - 9个ATP分子水解为ADP和无机磷酸。文中讨论了ATP酶活性和DNA酶活性可能的功能关系。
