| 摘 要： | 用离子-分子相互作用势函数,以Li~+,Na~+,Be~(2+),Mg~(2+)和(OH)_2PO_2~-形成的金属阳离子-磷酸阴离子络合物为模型,研究金属离子与核酸的相互作用。计算的相互作用能表明,由于金属离子对磷酸阴离子电荷分布的极化,使核酸构象发生改变。其阳离子作用顺序为Na~+

| Abstract: | The interaction between metal cation and nucleic acid have been studies by using an ion-molecule interaction potential function and a metal cation-phosphate anion complex model forming Li+, Na+, Be2+ and Mg2+ with (OH)2PO2-. Calculated interaction energies indicate that the change of nucleic acid conformation result from that the charge distribution of phosphate anion is subjected to polarization of the cation, The order cf effect of the cation is Na+
