The effect of several oligodeoxynucleotides complementary to the fragments of yellow lupin tRNA(Phe) was tested in the aminoacylation of tRNA(Phe) and in the binding of Phe-tRNA(Phe) to poly-U-programmed eukaryotic ribosomes. Oligonucleotides tested in the aminoacylation test did not give any inhibition. Monomers and dimers did not have any significant influence on the binding assay, either. A different percentage of inhibition of the binding of Phe-tRNA to ribosomes has been observed for oligonucleotides. Heptamer complementary to the anticodon loop gave 100% inhibition of the binding reaction. However, the oligonucleotides complementary to both the anticodon loop and stem and longer than the heptamer were much less effective inhibitors. A high inhibitory effect was also observed for trimers and for the decamer complementary to the D-loop and CCA-end.
