Abstract
To examine the role of the 5.8 S rRNA in ribosome function, oligodeoxyribonucleotides, complementary to chemically accessible sequences, were incubated with rabbit reticulocyte or wheat germ extracts undergoing protein synthesis in vitro. Significant and reproducible inhibitions were observed with several different oligonucleotides, the most inhibitory being specific for the universally conserved GAAC sequence. Mutant or heterologous sequences were substantially less inhibitory, results which clearly implicate the 5.8 S rRNA in the inhibitory process and are consistent with the possibility that the 5.8 S rRNA plays an important role in the binding of tRNA.
