| 英文摘要 | The interaction of neodymium ion (Nd3+) and lanthanum ion (La3+) with tRNA was studied by circular dichroism (CD) spectrum: The result showed that the peak 260 nm(+) was slightly blue shifted by 2 similar to 3 nm in the presence of 1.5 similar to 6 mu mol/L Nd3+ or La3+ and the amplitude of 260 nm (+) peak was increased by about 6% and 20% for Nd3+ and La3+ respectively. The peak 210 nm (-) blue or red shifted at difference molar ratio of Nd3+/tRNA for the native tRNA and Mg2+-free tRNA. The amplitude of the peak 210 nm(-) was increased or decreased by about 50%. These results indicated that the conformational change of tRNA was caused by the binding of Nd3+ and La3+ to tRNA. Eu3+ had some effect on the CD spectra of Escherichia coli Leucyl-tRNA Synthetase (LeuRS) and tRNA-LeuRS complex. |
