Abstract excerpt
A fluorescence titration assay was used to detect the effects of various modifications of E.coli elongation factor Tu on the formation of the ternary complex with aminoacyl-tRNAs. The treatment of EF-Tu.GDP with TPCK, an analogue of the 3'terminus of aminoacyl-tRNA, was found to have no influence on the conversion of EF-Tu.GDP to 'active' EF-Tu.GTP, but does decrease the affinity of the activated protein for...
