1V13, 1V14, 1V15 - PubMed Abstract: 
Controversy surrounds the metal-dependent mechanism of H-N-H endonucleases, enzymes involved in a variety of biological functions, including intron homing and DNA repair. To address this issue we determined the crystal structures for complexes of the H-N-H motif containing bacterial toxin colicin E9 with Zn(2+), Zn(2+) ...
