The inactivation of rec BC (D) DNase upon chromatography on DEAE-cellulose was observed. Simultaneously DNA-stimulated ATPases (I and II) and DNase activities on single- and double-stranded DNA substrates were measured in Escherichia coli rec+ and rec- cell extracts. Normal levels of ATPase I and II were detected in rec+ cells. Rec A- cells were lacking DNA dependent ATPase I, while rec B single and rec BC double mutants were defective in DNA dependent ATPase II, the second major enzyme of this type. Rec B and C mutations did not change DNase activities. Rec A mutation significantly increased DNase activity on linear single-stranded substrate.

Three DNA-dependent ATPases (gamma phosphohydrolases) can be isolated from Bacillus subtilis cells. We studied these enzymes in a number of mutants deficient in recombination or repair functions (rec, uvr) and in competent cells. The recA mutant studied had lower ATPase II activity, while competent cells had higher ATPase I activity, in comparison with the parental strain not brought to competence.
