| Abstract |
The binding ability of pyrrolidinyl peptide nucleic acid (PNA) binding to its complementary DNA and self-paring has been studied experimentally. However, a detailed understanding of the binding property is still unclear due to the lack of their crystallographic data. In this work, structural and energetic properties of PNA-DNA and PNA-PNA duplexes were studied using molecular dynamics (MD) simulations and quantum calculations. The studied pyrrolidinyl PNA backbone was (2R,4R)-prolyl-(1S,2S)-2-aminocyclobutanecarboxylic acid. MD simulations of three different forms (A–, B– and P–form) were performed in order to investigate the probable duplex conformation. As the results, PNA-PNA duplex exhibited the structural feature between A- and P-type conformations, while PNA-DNA double helix clearly showed the characteristic of B-form. In addition, quantum calculations revealed that the interaction of PNA-DNA duplex was larger than that of PNA-PNA duplex, indicating higher intrinsic stability of PNA-DNA compared to PNA-PNA double strand. This research may lead to a design of PNA for further applications. |
