In prokaryotes, three elongation factors are required for translation: EF-Tu, EF-Ts, and EF-G.
- EF-Tu (elongation factor thermo unstable) mediates the entry of the aminoacyl tRNA into a free site of the ribosome.
- EF-G catalyzes the translocation of the tRNA and mRNA down the ribosome at the end of each round of polypeptide elongation.
