'''Crystal Structure of a 70S Ribosome-tRNA Complex Reveals Functional Interactions and Rearrangements. This file, 2OW8, contains the 30S ribosome subunit, two tRNA, and mRNA molecules. 50S ribosome subunit is in the file 1VSA.'''
 
 
==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.
 
==About this Structure==
2OW8 is a [[Protein complex]] structure of sequences from [http://en.wikipedia.org/wiki/Escherichia_coli Escherichia coli] and [http://en.wikipedia.org/wiki/Thermus_thermophilus Thermus thermophilus]. This structure supersedes the now removed PDB entry [http://oca.weizmann.ac.il/oca-bin/send-pdb?obs=1&id=2i1c 2i1c]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=2OW8 OCA].
