Abstract

High-resolution cryo-electron microscopy shows that the Trypanosoma brucei kinetoplastid ribosome is characterized by the presence of large expansion segments, ribosomal-protein extensions and additional rRNA insertions, which may have implications for the protein-translation regulation process.
