Abstract excerpt

The nuclease NurA is present in all known thermophilic archaea and has been implicated to facilitate efficient DNA double-strand break end processing in Mre11/Rad50-mediated homologous recombinational repair. To understand the structural and functional relationship of this enzyme, we constructed five site-directed mutants of NurA from Sulfolobus tokodaii (StoNurA), D56A, E114A, D131A, Y291A, and H299A, at the...
