[Functional compartmentation of the translation apparatus and channeling of tRNA/aminoacyl-tRNA in cells of higher eukaryotes].
Literature data and authors' results in the field of structure-function organization of the translation apparatus in higher eukaryotes are considered. Proof is presented of the channeling of tRNA/aminoacyl-tRNA in the course of eukaryotic protein synthesis. The concept of the shuttle role of elongation factor eEF1A is grounded; the factor, being in a GTP-bound form, delivers aminoacyl-tRNA to the ribosome and then, in the GDP form after hydrolysis of GTP on the ribosome, forms a complex with the deacylated tRNA and delivers it to the aminoacyl-tRNA synthetase. The notion of translational compartment is defined.
