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 AddA nuclease domain is
CC required for chi fragment generation; this subunit has the helicase and
CC 3' -> 5' nuclease activities. {ECO:0000255|HAMAP-Rule:MF_01451}.
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:0000255|HAMAP-Rule:MF_01451};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01451};
CC -!- SUBUNIT: Heterodimer of AddA and AddB/RexB. {ECO:0000255|HAMAP-
CC Rule:MF_01451}.
CC -!- SIMILARITY: Belongs to the helicase family. AddA subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01451}.
