DESCRIPTION
Also known as ADDA_LACLM, addA, rexA. The heterodimer acts as both an ATP-dependent DNA helicase and an ATP-dependent, dual-direction single-stranded exonuclease. Recognizes the L.lactis chi site (5'-GCGCGTG-3'), which stimulates homologous recombination. The AddA nuclease domain is required for chi fragment generation; this subunit has 3'->5' exonuclease activity and probably also performs the helicase function. Heterodimer of AddA and RexB.
