Web8 dec. 2014 · 4.1. Interactions in POST Complexes. The first study on structural aspects of interactions of tRNA with the eukaryotic ribosome was a cryo-EM study with yeast 80S ribosome containing peptidyl-tRNA at the P site [ 15] (POST state with classical P/P configuration of the tRNA) solved at 15.4 Å resolution. WebIn the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released.
