Abstract

The translation factor 5A (eIF5A) is highly conserved in Archaea and eukaryotes and is essential for cell viability. This is the only protein known to contain the amino acid residue hypusine, essential for eIF5A function, generated by a post-translational modification. The functional homolog of eIF5A in bacteria is the EF- P factor. The crystal structure of EF-P bound to 70S ribosome shows that this factor is located between the P and E sites and the modification loop near the peptidyl transferase center of the ribosome. Using data from tRNA and rRNA hydroxyl radical cleavage it was modeled the eIF5A location on 80S similarly as reported for EF-P structure. These structural data suggest an EF-P/eIF5A function in peptide bond formation if the E site is not occupied. Besides eIF5A and EF- P have already been associated with the translation initiation, more recent studies have established a role specifically on the elongation of consecutive proline-containing sequences (poly- P), which are able to induce a ribosome stalling due to low reactivity of proline for peptide bond formation. However, different proteomic cellular profile studies concluded that not only polypeptides containing poly-P have its translation dependent on EF- P and the absence of this factor does not affect all poly-P polipeptides. An analysis integrating data from different studies led to the conclusion that residues immediately before and immediately after consecutive proline residues inducing ribossmoal stalling and the translation initiation rate and poly-P sequence position also affect the dependence of EF- P for protein translation. Still, there are few studies with proteomic profile in the absence of eIF5A function and the proteins which syntheses are dependent on eIF5A are not well known. Thus, the present study aims to search for the proteins which syntheses are dependent on eIF5A by proteomic profile comparison between wild-type strains and eIF5A mutants in Saccharomyces cerevisiae.
