  • Title: [Ef-Ts elongation factor interacts with elongation factor EF-Tu on ribosomes prior to the GTP hydrolysis stage].
    Author: Bubunenko MG, Gudkov AT.
    Journal: Mol Biol (Mosk); 1991; 25(1):172-6. PubMed ID: 1896033.
    Abstract:
    Methods of high-speed centrifugation and limited proteolysis were used to probe the interaction of EF-Tu with EF-Ts on the ribosome. It is shown that EF-Ts dissociates from EF-Tu only after EF-Tu-mediated GTP hydrolysis, i.e. EF-Ts within the EF-Tu.ribosome complexes in the pre-GTP-hydrolysis state co-sediments with the ribosomes and its rate of proteolysis is distinct from that of free EF-Ts. Moreover, as seen from the difference in sensitivity to trypsin of ribosomal proteins L19 and L27 EF-Ts affects the interaction of EF-Tu with the ribosome.
