Large-Scale Movements of IF3 and tRNA during Bacterial Translation Initiation
In bacterial translational initiation, three initiation factors (IFs 1-3) enable the selection of initiator tRNA and the start codon in the P site of the 30S ribosomal subunit. Here, we report 11 single-particle cryo-electron microscopy (cryoEM) reconstructions of the complex of bacterial 30S subunit with initiator tRNA, mRNA, and IFs 1-3, representing different steps along the initiation pathw...
متن کاملStructural dynamics of bacterial translation initiation factor IF2.
Bacterial translation initiation factor IF2 promotes ribosomal subunit association, recruitment, and binding of fMet-tRNA to the ribosomal P-site and initiation dipeptide formation. Here, we present the solution structures of GDP-bound and apo-IF2-G2 of Bacillus stearothermophilus and provide evidence that this isolated domain binds the 50 S ribosomal subunit and hydrolyzes GTP. Differences bet...
متن کاملThe fidelity of translation initiation: reciprocal activities of eIF1, IF3 and YciH.
Eukaryotic initiation factor eIF1 and the functional C-terminal domain of prokaryotic initiation factor IF3 maintain the fidelity of initiation codon selection in eukaryotes and prokaryotes, respectively, and bind to the same regions of small ribosomal subunits, between the platform and initiator tRNA. Here we report that these nonhomologous factors can bind to the same regions of heterologous ...

15 صفحه اولconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
