After the ribosome structure: how does translocation work?

RNA. 2003 Feb;9(2):160-4. doi: 10.1261/rna.2163103.

Abstract

Structures of the ribosomal large and small subunits have been solved to atomic resolution by X-ray crystallography. These structures provide a new foundation to address the complex process of protein biosynthesis by the ribosome. Translocation of the tRNA-mRNA complex is one of the most fascinating tasks performed by the ribosome. The impact of the crystal structures in understanding the molecular mechanism of translocation is highlighted in this review.
