  1. Fu J, Momcilovic I, Clemente T, Nersesian N, Trick H, Ristic Z. Heterologous expression of a plastid EF-Tu reduces protein thermal aggregation and enhances CO2 fixation in wheat (Triticum aestivum) following heat stress. Plant Mol Biol. 2008;68:277-88 pubmed publisher
    ..The results strongly suggest that heat tolerance of wheat, and possibly other crop plants, can be improved by modulating expression of plastidal EF-Tu and/or by selection of genotypes with increased endogenous levels of this protein. ..

    ..Moreover, the results also support the hypothesis that EF-Tu contributes to heat tolerance by acting as a molecular chaperone and protecting heat-labile proteins from thermal aggregation in a non-specific manner. ..

    ..1; chi squared, P = .45). Phylogenetically, all sequences from positive specimens matched E faecalis V583 (AE016947). Conclusion E faecalis was the only enterococcal species detected, with an overall prevalence of 22%. ..

    ..The results are consistent with the hypothesis that chloroplast EF-Tu plays a functional role in heat tolerance by acting as a molecular chaperone. ..

    ..Alternatively on full proteomics analysis elongation factor Tu generally provided the highest confidence in staphylococcal speciation. ..
  8. Wower I, Wower J, Zimmermann R. Ribosomal protein L27 participates in both 50 S subunit assembly and the peptidyl transferase reaction. J Biol Chem. 1998;273:19847-52 pubmed
    ..We therefore infer that L27 contributes to peptide bond formation by facilitating the proper placement of the acceptor end of the A-site tRNA at the peptidyl transferase center. ..
  9. Ristic Z, Bukovnik U, Momcilovic I, Fu J, Vara Prasad P. Heat-induced accumulation of chloroplast protein synthesis elongation factor, EF-Tu, in winter wheat. J Plant Physiol. 2008;165:192-202 pubmed
    ..Young plants of all cultivars but one did not show significant increases in the relative levels of EF-Tu. The results of the study suggest that EF-Tu protein may play a role in heat tolerance in winter wheat. ..

    ..These data indicate that the in vivo degradation of tufA mRNA begins in the 5' UTR, and is promoted by translation. The data also suggest, however, that the level of the mature RNA is determined more by the 3' UTR than the 5' UTR...
