Adenosine Triphosphate 17-20 RAD50 double strand break repair protein Homo sapiens 81-86 10346816-5 1999 On nonhairpin DNA ends, ATP controls a switch in endonuclease specificity that allows Mre11/Rad50/Nbs1 to cleave a 3"-protruding strand at a double-/single-strand transition. Adenosine Triphosphate 24-27 RAD50 double strand break repair protein Homo sapiens 92-97 10346816-6 1999 Mutational analysis demonstrates that Rad50 is responsible for ATP binding by the complex, but the ATP-dependent activities are expressed only with Nbs1 present. Adenosine Triphosphate 63-66 RAD50 double strand break repair protein Homo sapiens 38-43
