Journal ArticleDOI
Solution structure of the ribosome-binding domain of E. coli translation initiation factor IF3. Homology with the U1A protein of the eukaryotic spliceosome.
TL;DR: A convergent evolution process for E. coli IF3 and U1A small nuclear ribonucleoprotein structure, which binds to the U1 snRNA in the eukaryotic spliceosome, suggests a convergent evolved process for these two proteins that are associated with ribon nucleoproteic complexes.
Journal ArticleDOI
Heteronuclear NMR studies of E. coli translation initiation factor IF3. Evidence that the inter-domain region is disordered in solution.

TL;DR: Heteronuclear relaxation studies of a sample selectively labelled on lysine residues demonstrates that the inter-domain linker is highly flexible, exhibiting increased 15N T2 values and negative 1H[15N] nuclear Overhause effects over a length of at least eight residues.
Journal ArticleDOI
1H and 15N resonance assignments and structure of the N-terminal domain of Escherichia coli initiation factor 3.
TL;DR: Since the heteronuclear 1H-15N correlation spectrum of the N-terminal domain of IF3 is an almost exact subset of that of the native protein, the assignments obtained and the structure calculated should be directly transposable to the full-length protein.
Journal ArticleDOI
The N-terminal half of initiation factor IF3 is folded as a stable independent domain.
TL;DR: The domain structure of IF3 from Escherichia coli has been investigated by limited proteolysis followed by mass spectrometry and protein sequencing of the resulting peptides and revealed a highly segmented structure with two independent domains connected by a charged linker peptide, highly susceptible to proteolytic cleavage.
