CC -!- FUNCTION: The heterodimer acts as both an ATP-dependent DNA helicase
CC and an ATP-dependent, dual-direction single-stranded exonuclease.
CC Recognizes the chi site generating a DNA molecule suitable for the
CC initiation of homologous recombination. The AddB subunit has 5' -> 3'
CC nuclease activity but not helicase activity. {ECO:0000255|HAMAP-
CC Rule:MF_01452}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01452};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01452};
CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000255|HAMAP-Rule:MF_01452};
CC -!- SUBUNIT: Heterodimer of AddA and AddB. {ECO:0000255|HAMAP-
CC Rule:MF_01452}.
CC -!- MISCELLANEOUS: Despite having conserved helicase domains, this subunit
CC does not have helicase activity. {ECO:0000255|HAMAP-Rule:MF_01452}.
CC -!- SIMILARITY: Belongs to the helicase family. AddB/RexB type 1 subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01452}.
