|Title:||Impact of Cu(II) and Ni(II) on a structure of chiral peptide nucleic acids having four, six and eight thymines in a peptide side chain||Authors:||J., Brasun
|Issue Date:||2001||Project:||None||Journal:||JOURNAL OF INORGANIC BIOCHEMISTRY||Abstract:||
The studies on binding ability of longer chiral peptide nucleic acids (having four, six and eight thymines in a peptide side chain) have shown that the interactions between the nucleic base rings within a ligand molecule have a critical impact on the complex stability. Thymines inserted in the peptide side chain interact with each other as well as with peptide back-bone increasing the structural organization of the cPNA molecule. The metal ion coordination to cPNA, on the other hand, induces a very specific ligand structure, which may have a basic impact on the cPNA self-recognition processes. (C) 2001 Elsevier Science B.V.
