The P. furiosus Mre11/Rad50 Complex Promotes 5′ Strand Resection at a DNA Double-Strand Break

The Mre11/Rad50 complex has been implicated in the early steps of DNA double-strand break (DSB) repair through homologous recombination in several organisms. However, the enzymatic properties of this complex are incompatible with the generation of 3′ single-stranded DNA for recombinase loading and strand exchange. In thermophilic archaea, the Mre11 and Rad50 genes cluster in an operon with genes encoding a helicase, HerA, and a 5′ to 3′ exonuclease, NurA, suggesting a common function
