Function

[EFTU1_THETH] This protein promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis. [EFTS_THET8] Associates with the EF-Tu.GDP complex and induces the exchange of GDP to GTP. It remains bound to the aminoacyl-tRNA.EF-Tu.GTP complex up to the GTP hydrolysis stage on the ribosome.

Publication Abstract from PubMed

In order to study nucleotide exchange mechanisms in GTP-binding proteins, we have determined the crystal structure of the complex formed by the elongation factor Tu (EF-Tu) and its exchange factor Ts (EF-Ts) from Thermus thermophilus. The complex is a dyad symmetrical heterotetramer in which each EF-Tu, through a bipartite interface, interacts with two subunits of EF-Ts, explaining the need for a dimeric exchange factor. The architecture of the assembly is distinctly different from that of the corresponding heterodimeric E. coli complex, in which the monomeric E. coli EF-Ts remarkably forms essentially the same bipartite interface with EF-Tu through a sequence/structural repeat. GDP is released primarily by a Ts-induced peptide flip in the nucleotide binding pocket that disrupts hydrogen bonds to the phosphates and repositions the peptide carbonyl so as to sterically and electrostatically eject the GDP. The exchange mechanism may have useful implications for receptor-induced exchange in heterotrimeric G proteins.
