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=5.6.2.4;
CC Evidence={ECO:0000256|ARBA:ARBA00034618};
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}.
CC -!- DOMAIN: The N-terminal DNA-binding domain is a ssDNA-dependent ATPase
CC and has ATP-dependent 3'-5' helicase function. This domain interacts
CC 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 -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
