CC -!- FUNCTION: A helicase/nuclease that prepares dsDNA breaks (DSB) for CC recombinational DNA repair. Binds to DSBs and unwinds DNA via a CC highly rapid and processive ATP-dependent bidirectional helicase CC activity. Unwinds dsDNA until it encounters a Chi (crossover CC hotspot instigator) sequence from the 3' direction. Cuts ssDNA a CC few nucleotides 3' to the Chi site. The properties and activities CC of the enzyme are changed at Chi. The Chi-altered holoenzyme CC produces a long 3'-ssDNA overhang and facilitates RecA-binding to CC the ssDNA for homologous DNA recombination and repair. Holoenzyme CC degrades any linearized DNA that is unable to undergo homologous CC recombination. In the holoenzyme this subunit contributes ATPase, CC 3'-5' helicase, exonuclease activity and loads RecA onto ssDNA. CC {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- CATALYTIC ACTIVITY: Exonucleolytic cleavage (in the presence of CC ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'- CC phosphooligonucleotides. {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01485}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01485}; CC -!- SUBUNIT: Heterotrimer of RecB, RecC and RecD. All subunits CC contribute to DNA-binding. Interacts with RecA. CC {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- DOMAIN: The C-terminal domain has nuclease activity and interacts CC with RecD. It interacts with RecA, facilitating its loading onto CC ssDNA. {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- DOMAIN: The N-terminal DNA-binding domain is a ssDNA-dependent CC ATPase and has ATP-dependent 3'-5' helicase function. This domain CC interacts with RecC. {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- SIMILARITY: Belongs to the helicase family. UvrD subfamily. CC {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- SIMILARITY: Contains 1 uvrD-like helicase ATP-binding domain. CC {ECO:0000256|HAMAP-Rule:MF_01485}. CC -!- SIMILARITY: Contains 1 uvrD-like helicase C-terminal domain. CC {ECO:0000256|HAMAP-Rule:MF_01485}.
