520 3 |a Molecular dynamic simulations have been performed to investigate the DNA binding affinities and cleavage activities of a new class of copper nucleases with similar ligand structures, including Cu(pzdpy)2+, Cu(hpzpy)2+, Cu(pmea)2+, Cu(pmap)2+, Cu(tepa)2+ and Cu(tpa)2+, in this present study. The obtained results reveal that the five copper nucleases bind to DNA in the minor groove, while the favorable binding sites for Cu(tepa)2+ locate in the DNA major groove. Analyses of binding free energies, all possible hydrogen bonds and favorable interactions between copper nucleases and DNA suggest that DNA binding affinities of the six copper nucleases are in the order of Cu(pzdpy)2+>Cu(hpzpy)2+>Cu(pmea)2+>Cu(tepa)2+>Cu(tpa)2+>Cu(pmap)2+, which is good agreement with the experimental results. Meanwhile, the simulated results demonstrated that significant difference in frequency distribution of the DNA helical parameters was observed between the unbound B-DNA and the bound DNA by the copper nucleases, which causes the inhibition of transcription and replication. Furthermore, RDF analyses suggest that the activities of the studied copper nucleases decrease in the order of Cu(pzdpy)2+, Cu(pmea)2+, Cu(hpzpy)2+, Cu(tpa)2+, Cu(pmap)2+ and Cu(tepa)2+, consisting with the experimental results. The present study provides detailed information to help us understand a new congeneric class of copper nucleases with different nuclease properties.
