1 To understand how the ribosome triggers GTP hydrolysis in translational GTPases, we have determined the crystal structure of EF-Tu and aminoacyl-tRNA bound to the ribosome with a GTP analog, to 3.2 angstrom resolution. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens

3 EF-Tu is in its active conformation, the switch I loop is ordered, and the catalytic histidine is coordinating the nucleophilic water in position for inline attack on the gamma-phosphate of GTP. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
