Abstract
Elongation factors EF‐G and EF‐Tu are structural homologues and share near‐identical binding sites on the ribosome, which encompass the GTPase‐associated centre (GAC) and the sarcin‐ricin loop (SRL). The SRL is fixed structure in the ribosome and contacts elongation factors in the vicinity of their GTP‐binding site. In contrast, the GAC is mobile and we hypothesize that it interacts with the alpha helix D of the EF‐Tu G‐domain in the same way as with the alpha helix A of the G′‐domain of EF‐G. The mutual locations of these helices and GTP‐binding sites in the structures of EF‐Tu and EF‐G are different. Thus, the orientation of the GAC relative to the SRL determines whether EF‐G or EF‐Tu will bind to the ribosome.
