In This Issue Closing In on DSB Recognition PAGE 54 DNA double-strand breaks (DSBs) pose a threat to genome stability and can lead to cancer. The MR complex, containing the Mre11 nuclease and the Rad50 ABC ATPase, is a key sensor and processing factor for DSBs. Using structural, biochemical, and genetic studies, Lammens et al. show that the bacterial MR complex is an ATP-controlled DNA clamp. ATP induces MR to change from an open loading form into a compact DNA binding form, revealing how MR
