I found a couple of higher affinity, Inhibitory (nM) ss DNA aptamers towards my target protein through DNA SELEX and now very keen to study the possible DNA aptamer-Protein interactions (binding site). I have predicted secondary structures of my ssDNA aptamers by Mfold programme, however I did not find any programme to predict tertiary (3D) structure, which generates PDB/PDBQT file of the DNA aptamers as needed by many ligand-protein docking programme. Thus, I would highly appreciate, if you could please lend me your valuable suggestion/advice to address this issue.
