title: Resolution and reconstitution of the rec BC deoxyribonuclease of Escherichia coli.
abstract: The inactivation of rec BC nuclease activity and simultaneously the separation of 3 DNA-dependent ATPases and an ATP-independent DNases specific for single-stranded DNA have been observed after DEAE-cellulose chromatography of cell extracts from Escherichia coli. Two of the ATPases catalyze the strand separation of duplex DNA. Reconstitution of ATP-dependent DNase activity has been carried out by the combination of the separated enzymes.
