Description: Eukaryotic eIF-5A was initially thought to function as a translation initiation factor, based on its ability to stimulate methionyl-puromycin synthesis. However, subsequent work revealed a role for eIF5A in translation elongation [, ]. Depletion or inactivation of eIF-5A in the yeast Saccharomyces cerevisiae (Baker's yeast) resulted in the accumulation of polysomes and an increase in ribosomal transit times. Addition of recombinant eIF-5A from yeast, but not a derivative lacking hypusine, enhanced the rate of tripeptide synthesis in vitro. Moreover, inactivation of eIF-5A mimicked the effects of the eEF2 inhibitor sordarin, indicating that eIF-5A might function together with eEF2 to promote ribosomal translocation. Finally, it was shown that eIF5A is specifically required to promote peptide-bond formation between consecutive proline residues.

Description: Eukaryotic eIF-5A was initially thought to function as a translation initiation factor, based on its ability to stimulate methionyl-puromycin synthesis. However, subsequent work revealed a role for eIF5A in translation elongation [, ]. Depletion or inactivation of eIF-5A in the yeast Saccharomyces cerevisiae (Baker's yeast) resulted in the accumulation of polysomes and an increase in ribosomal transit times. Addition of recombinant eIF-5A from yeast, but not a derivative lacking hypusine, enhanced the rate of tripeptide synthesis in vitro. Moreover, inactivation of eIF-5A mimicked the effects of the eEF2 inhibitor sordarin, indicating that eIF-5A might function together with eEF2 to promote ribosomal translocation. Finally, it was shown that eIF5A is specifically required to promote peptide-bond formation between consecutive proline residues. It has been proposed to stimulate the peptidyl-transferase activity of the ribosome and facilitate the reactivity of poor substrates like proline [].eIF-5A is a cofactor for the Rev and Rex transactivator proteins of human immunodeficiency virus-1 and T-cell leukaemia virus I, respectively [, , ].

Woronin bodies are important for stress resistance and virulence [].
