CC -!- FUNCTION: A helicase/nuclease that prepares dsDNA breaks (DSB) for
CC recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly
CC rapid and processive ATP-dependent bidirectional helicase activity.
CC Unwinds dsDNA until it encounters a Chi (crossover hotspot instigator)
CC sequence from the 3' direction. Cuts ssDNA a few nucleotides 3' to the
CC Chi site. The properties and activities of the enzyme are changed at
CC Chi. The Chi-altered holoenzyme produces a long 3'-ssDNA overhang and
CC facilitates RecA-binding to the ssDNA for homologous DNA recombination
CC and repair. Holoenzyme degrades any linearized DNA that is unable to
CC undergo homologous recombination. In the holoenzyme this subunit has
CC ssDNA-dependent ATPase and 5'-3' helicase activity. When added to pre-
CC assembled RecBC greatly stimulates nuclease activity and augments
CC holoenzyme processivity. Negatively regulates the RecA-loading ability
CC of RecBCD. {ECO:0000256|HAMAP-Rule:MF_01487}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exonucleolytic cleavage (in the presence of ATP) in either
CC 5'- to 3'- or 3'- to 5'-direction to yield 5'-
CC phosphooligonucleotides.; EC=3.1.11.5; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01487};
CC -!- SUBUNIT: Heterotrimer of RecB, RecC and RecD. All subunits contribute
CC to DNA-binding. {ECO:0000256|HAMAP-Rule:MF_01487}.
CC -!- SIMILARITY: Belongs to the RecD family. {ECO:0000256|HAMAP-
CC Rule:MF_01487}.
