tRNA-rRNA interactions and peptidyl transferase.

The extent to which ribosomal RNA is directly involved in the function of ribosomes has important implications for both the mechanism of translation and the molecular origins of life. Detailed evidence has accumulated that places the anticodon and acceptor ends of tRNA in close proximity to conserved features of rRNA in the ribosome. Recent studies are providing evidence that these features are important for ribosomal function.
