1 Eukaryotic elongation factor eEF1A transits between the GTP- and GDP-bound conformations during the ribosomal polypeptide chain elongation. Guanosine Diphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
2 Correct codon-anticodon recognition triggers GTP hydrolysis, with subsequent dissociation of eEF1A*GDP from the ribosome. Guanosine Diphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
3 Here, we report the first crystal structure of the mammalian eEF1A2*GDP complex which indicates major differences in the organization of the nucleotide-binding domain and intramolecular movements of eEF1A compared to EF-Tu. Guanosine Diphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
4 Here, we report the first crystal structure of the mammalian eEF1A2*GDP complex which indicates major differences in the organization of the nucleotide-binding domain and intramolecular movements of eEF1A compared to EF-Tu. Guanosine Diphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
5 Our results explain the nucleotide exchange mechanism in the mammalian eEF1A and suggest that the first step of eEF1A*GDP dissociation from the 80S ribosome is the rotation of the nucleotide-binding domain observed after GTP hydrolysis. Guanosine Diphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
