An epitope of elongation factor Tu (EF-Tu), which is found in organisms in both the bacterial and archaeal domains, was recently defined by mAb 900. To localize the conserved epitope within the EF-Tu molecule and to determine its sequence, SPOTScan analysis of synthetic peptides, Western blot analysis of purified EF-Tu domains and site-directed mutagenesis studies were used. Analysis of mAb 900 binding to overlapping 15-mer peptides encompassing the complete sequence of EF-Tu of Escherichia coli was inconclusive, suggesting three distinct regions may be epitopes. Western blot analysis of EF-Tu domains 1-3 of Thermus thermophilus suggested that the epitope was located at the N terminus. This was confirmed by site-directed mutagenesis of EF-Tu domain 1 of Mycoplasma hominis. By C-terminal truncation of the N-terminal 15-mer peptide the epitope was mapped to EF-Tu residues 1-6. Replacement of each of the residues in the epitope peptide demonstrated that only positions 5 and 6 were indispensable for
Electron paramagnetic resonance spectroscopy has been used to obtain information on the structure and stability of the products of GTP cleavage at the active site of elongation factor Tu (EF-Tu) from Bacillus stearothermophilus. Using stereospecifically labelled (Sp)-(Rp)-[beta-17O]GTP (prepared by modification of a previously published procedure which is now also suitable for guanine nucleotides), it was found that only one of the two possible diastereomers (Sp) led to detectable line-broadening of the EPR spectrum of Mn2+ at the active site of EF-Tu (linewidth 1.5 mT), whereas the Rp isomer caused the same linewidth as unlabelled nucleotide (1.3 mT). From our earlier work and from a demonstration that the lifetime of the state giving the broadened spectrum is too long to be assigned to the EF-Tu.GDP.Mn complex [the rate constant for decay as measured by displacement of GDP by the fluorescent 2(3)-O-(N-methylanthraniloyl)-GDP is 6.2 x 10(-3) s-1 at 25 degrees C and pH 6.8], we conclude that ...
Elongation factor thermal unstable Tu (EF-Tu) is a G protein that catalyzes the binding of aminoacyl-tRNA to the A-site of the ribosome inside living cells. Structural and biochemical studies have described the complex interactions needed to effect canonical function. However, EF-Tu has evolved the capacity to execute diverse functions on the extracellular surface of both eukaryote and prokaryote cells. EF-Tu can traffic to, and is retained on, cell surfaces where can interact with membrane receptors and with extracellular matrix on the surface of plant and animal cells. Our structural studies indicate that short linear motifs (SLiMs) in surface exposed, non-conserved regions of the molecule may play a key role in the moonlighting functions ascribed to this ancient, highly abundant protein. Here we explore the diverse moonlighting functions relating to pathogenesis of EF-Tu in bacteria and examine putative SLiMs on surface-exposed regions of the molecule.

Ribosomes are the particles that catalyse mRNA-directed protein synthesis in all organisms. The codons of the mRNA are exposed on the ribosome to allow tRNA binding. This leads to the incorporation of amino acids into the growing polypeptide chain in accordance with the genetic information. Incoming amino acid monomers enter the ribosomal A site in the form of aminoacyl-tRNAs complexed with elongation factor Tu (EF-Tu) and GTP. The growing polypeptide chain, situated in the P site as peptidyl-tRNA, is then transferred to aminoacyl-tRNA and the new peptidyl-tRNA, extended by one residue, is translocated to the P site with the aid the elongation factor G (EF-G) and GTP as the deacylated tRNA is released from the ribosome through one or more exit sites [PUBMED:11297922, PUBMED:11290319]. About 2/3 of the mass of the ribosome consists of RNA and 1/3 of protein. The proteins are named in accordance with the subunit of the ribosome which they belong to - the small (S1 to S31) and the large (L1 to ...
1ETU: Structural details of the binding of guanosine diphosphate to elongation factor Tu from E. coli as studied by X-ray crystallography.
PD mutations in the RocCOR domain of LRRK2 lead to a decrease in GTPase activity [23,25,43,44,56-58], although the affected residues are most often not directly located in the GTP/GDP-binding pocket [37,46]. Using the bacterial CtRoco as a model, we previously showed that the RocCOR domain needs to cycle between a dimeric and monomeric state during the GTPase reaction, where GTP binding induces monomerization while the protein re-dimerizes after GTP hydrolysis [36]. This mechanism thus predicts that either mutations that stabilize the dimer or that block the protein in a monomeric state would impair the GTPase reaction. We concomitantly showed that the L487A mutation (corresponding to the PD-associated mutation I1371V in LRRK2) leads to a decrease in GTP turnover and stabilizes the CtRoco dimer. In agreement with these findings and with our model, it was very recently reported that the R1441G/C/H and N1473H PD mutations decrease the GTPase activity of the Roc domain of LRRK2 by destabilizing or ...

The Gtr1 protein of Saccharomyces cerevisiae is a member of the RagA subfamily of the Ras-like small GTPase superfamily. Gtr1 has been implicated in various cellular processes. Particularly, the Switch regions in the GTPase domain of Gtr1 are essential for TORC1 activation and amino acid signaling. Therefore, knowledge about the biochemical activity of Gtr1 is required to understand its mode of action and regulation. By employing tryptophan fluorescence analysis and radioactive GTPase assays, we demonstrate that Gtr1 can adopt two distinct GDP- and GTP-bound conformations, and that it hydrolyses GTP much slower than Ras proteins. Using cysteine mutagenesis of Arginine-37 and Valine-67, residues at the Switch I and II regions, respectively, we show altered GTPase activity and associated conformational changes as compared to the wild type protein and the cysteine-less mutant. The extremely low intrinsic GTPase activity of Gtr1 implies requirement for interaction with activating proteins to support its
