Guanosine Diphosphate 181-184 G elongation factor mitochondrial 1 Homo sapiens 176-180 9678602-4 1998 Since it mimics the structure of the ternary complex of EF-Tu:GTP with aminoacyl-tRNA, which subsequently binds to the ribosome, EF-G:GDP leaves an imprint on the ribosome for the ternary complex. Guanosine Diphosphate 134-137 G elongation factor mitochondrial 1 Homo sapiens 129-133 9678602-3 1998 Furthermore, the structure of EF-G:GDP is the form of EF-G that dissociates from the ribosome. Guanosine Diphosphate 35-38 G elongation factor mitochondrial 1 Homo sapiens 54-58 9254632-2 1997 Crystallographic investigations have revealed that EF-G.GDP resembles the EF-Tu.GTP. Guanosine Diphosphate 56-59 G elongation factor mitochondrial 1 Homo sapiens 51-55 9254632-5 1997 However, its significance is uncertain because the affinity of EF-G.GDP for the ribosome is much lower than that of the ternary complex it resembles and because EF-Tu.GDP, the form of EF-Tu that has low ribosome affinity, has a conformation radically different from that of EF-Tu.GTP or EF-Tu in the ternary complex.

Guanosine Diphosphate 53-56 G elongation factor mitochondrial 1 Homo sapiens 17-36 8736554-2 1996 During translocation EF-G passes through four main conformational states: the GDP complex, the nucleotide-free state, the GTP complex, and the GTPase conformation. Guanosine Diphosphate 78-81 G elongation factor mitochondrial 1 Homo sapiens 21-25 8736554-4 1996 RESULTS: The structure of EF-G-GDP has been refined at 2.4 A resolution. Guanosine Diphosphate 31-34 G elongation factor mitochondrial 1 Homo sapiens 26-30 8736554-7 1996 The magnesium ion is absent in EF-G-GDP. Guanosine Diphosphate 36-39 G elongation factor mitochondrial 1 Homo sapiens 31-35 8642600-7 1996 The revertant mutations probably restore the balance between the GDP and GTP conformations of EF-G off the ribosome, and most of them are located close to the interface between the G domain and domain II. Guanosine Diphosphate 65-68 G elongation factor mitochondrial 1 Homo sapiens 94-98 10397336-9 1998 The structural comparison of this ternary complex with the structure of EF-G:GDP displays an unexpected macromolecular mimicry, where three domains of EF-G mimick the shape of the tRNA in the ternary complex.
