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 nuclease domain is not
CC       required for chi fragment generation; this subunit has 5' -> 3'
CC       nuclease activity. {ECO:0000255|HAMAP-Rule:MF_01452}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,

CC   -!- SUBUNIT: Heterodimer of AddA and AddB. {ECO:0000255|HAMAP-
CC       Rule:MF_01452}.
CC   -!- SIMILARITY: Belongs to the helicase family. AddB/RexB type 1 subfamily.
