[[http://www.uniprot.org/uniprot/EFTS_ECOLI EFTS_ECOLI]] 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.[HAMAP-Rule:MF_00050]  
[https://www.uniprot.org/uniprot/EFTU2_ECOLI EFTU2_ECOLI] This protein promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis.[HAMAP-Rule:MF_00118]  May play an important regulatory role in cell growth and in the bacterial response to nutrient deprivation.[HAMAP-Rule:MF_00118]

== Publication Abstract from PubMed ==
The crystal structure of the EF-Tu.EF-Ts complex from Escherichia coli has been determined to a resolution of 2.5 A. The complex contains two subunits of each of the elongation factors. The two EF-Ts molecules form a tight dimer, but there is little contact between the two EF-Tu molecules. The interaction of EF-Ts with EF-Tu results principally in the disruption of the Mg2+ ion binding site, thereby reducing the affinity of EF-Tu for guanine nucleotides.
The structure of the Escherichia coli EF-Tu.EF-Ts complex at 2.5 A resolution.,Kawashima T, Berthet-Colominas C, Wulff M, Cusack S, Leberman R Nature. 1996 Feb 8;379(6565):511-8. PMID:8596629<ref>PMID:8596629</ref>
