==Overview==
==Overview==
Our understanding of the mechanism of protein synthesis has undergone, rapid progress in recent years as a result of low-resolution X-ray and, cryo-EM structures of ribosome functional complexes and high-resolution, structures of ribosomal subunits and vacant ribosomes. Here, we present, the crystal structure of the Thermus thermophilus 70S ribosome containing, a model mRNA and two tRNAs at 3.7 A resolution. Many structural details of, the interactions between the ribosome, tRNA, and mRNA in the P and E sites, and the ways in which tRNA structure is distorted by its interactions with, the ribosome are seen. Differences between the conformations of vacant and, tRNA-bound 70S ribosomes suggest an induced fit of the ribosome structure, in response to tRNA binding, including significant changes in the, peptidyl-transferase catalytic site.
