Abstract
A series of conjugates of peptide nucleic acids (PNA) and Zr(IV) complexes was prepared. Their ability to hydrolyze DNA was tested using MALDI-TOF mass spectrometry and HPLC. The most efficient artificial restriction enzyme found, PNA conjugate with Zr(IV) complex of tris(hydroxymethyl)-aminomethane, cleaves DNA targets sequence selectively in close proximity to the Zr(IV) complex. It was demonstrated that cleavage products are substrates of terminal transferase.
