Release of (oligo) peptidyl-tRNA from ribosomes by erythromycin A.
Erythromycin A released peptidyl-tRNA in the in vitro polypeptide synthesis system with bacterial components programmed by synthetic polynucleotide. This is consistent with our hypothesis that erythromycin A inhibits translocation by preventing proper situation of oligopeptidyl-tRNA in the donor (D) site on ribosomes.
متن کاملInhibition by siomycin and thiostrepton of both aminoacyl-tRNA and factor G binding to ribosomes.
Siomycin, a peptide antibiotic that interacts with the 50S ribosomal subunit and inhibits binding of factor G, is shown also to inhibit binding of aminoacyl-tRNA; however, it does not impair binding of fMet-tRNA and completion of the initiation complex. Moreover, unlike other inhibitors of aminoacyl-tRNA binding (tetracycline, sparsomycin, and streptogramin A), siomycin completely abolishes the...
متن کاملInhibition by elongation factor EF G of aminoacyl-tRNA binding to ribosomes.
Elongation factor G (EF G), bound to ribosomes either with GMPPCP or with fusidic acid and GDP, inhibits elongation factor Tu (EF Tu)-dependent binding of Phe-tRNA on the ribosome-poly(U) complex and binding of Ala-tRNA on the initiation complex formed with RNA from bacteriophage R17; GTP hydrolysis associated with Phe-tRNA binding is also inhibited. Moreover, nonenzymic binding of Phe-tRNA at ...

15 صفحه اولFast recycling of Escherichia coli ribosomes requires both ribosome recycling factor (RRF) and release factor RF3.
A complete translation system has been assembled from pure initiation, elongation and termination factors as well as pure aminoacyl-tRNA synthetases. In this system, ribosomes perform repeated rounds of translation of short synthetic mRNAs which allows the time per translational round (the recycling time) to be measured. The system has been used to study the influence of release factor RF3 and ...
