Structural and functional study for tRNA cleavage by Glycine o-phenanthroline Cu-II complex, [CuCl(phen)(gly)]center dot 4H(2)O
The o-phenanthroline gly Cu(II) complex, [CuCl(phen)(gly)]center dot 4H(2)O 1, has been prepared and structurally characterized. The transfer RNA binding and degradation properties of complex 1 have been investigated by UV-vis spectroscopy, cyclic voltammetry (CV), capillary electrophoresis (CE) and atomic force microscopy (AFM) methods. The results showed that 1 can efficiently cleave tRNA in the physiological conditions (pH 7.0, and 37 degrees C), and has a digestion coefficient nearly up to 100% within 75 h. AFM image for 1/RNA exhibited arrayed tandem repetitions of tRNA segments. This study is targeting the destruction of the high-order structures of genetic biomacromolecules which paves an important way to novel materials for the decontamination of microorganisms (e.g., bacteria and viruses).
