Mapping metal ions at the catalytic centres of two intron-encoded endonucleases.
Divalent metal ions play a crucial role in forming the catalytic centres of DNA endonucleases. Substitution of Mg2+ ions by Fe2+ ions in two archaeal intron-encoded homing endonucleases, I-DmoI and I-PorI, yielded functional enzymes and enabled the generation of reactive hydroxyl radicals within the...
