Control of tRNA function by antisense PNA derivatives.

The interaction of antisense peptide nucleic acid (PNA) with yeast tRNA(Phe) was investigated. A 6-mer PNA complementary to the 3'-terminal sequence including the 73ACCA end hybridized to the tRNA. While the PNA with a single mismatch did not. PNA is a promising candidate for controlling tRNA functions by the sequence-specific hybridization.
