A Template-Mediated Click-Click Reaction: PNA-DNA, PNA-PNA (or Peptide) Ligation, and Single Nucleotide Discrimination.

ABSTRACT: A highly efficient chemical ligation was developed for quantitative conjugation of PNA with DNA (PNA or peptide) using the copper-catalyzed azide-alkyne cycloaddition reaction. While PNAs with an alkyne at the C-terminus and an azide at the N-terminus have been used, an efficient click-click reaction occurs. The PNA click ligation is sequence-specific and capable of single nucleotide discrimination.
