Insights into Chi recognition from the structure of an AddAB-type helicase–nuclease complex

In bacterial cells, processing of double-stranded DNA breaks for repair by homologous recombination is dependent upon the recombination hotspot sequence Chi and is catalysed by either an AddAB- or RecBCD-type helicase–nuclease. Here, we report the crystal structure of AddAB bound to DNA. The structu...
