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. Degrades ssDNA until it encounters a chi (crossover CC hotspot instigator) sequence from the 3' direction. Cuts DNA near CC or within the chi site, which attenuates 3'- but not 5'- CC exonuclease activity. The altered holoenzyme produces a long 3'- CC ssDNA overhang and facilitates RecA-binding to the ssDNA for CC homologous DNA recombination and repair. Holoenzyme degrades CC foreign DNA, contributing to antiviral protection. This subunit CC has DNA-dependent ATPase activity, exo- and endonuclease activity, CC 3'-5' helicase 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}.
