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 CC contributes ATPase, 3'-5' helicase, exonuclease activity and loads RecA CC onto ssDNA. {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12; CC Evidence={ECO:0000256|ARBA:ARBA00001665}; 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_01485}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01485}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01485}; CC -!- SUBUNIT: Heterotrimer of RecB, RecC and RecD. All subunits contribute CC to DNA-binding. Interacts with RecA. {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- DOMAIN: The C-terminal domain has nuclease activity and interacts with CC RecD. It interacts with RecA, facilitating its loading onto ssDNA. CC {ECO:0000256|HAMAP-Rule:MF_01485}.
