      DescriptionAnti-Hypusine
      Alternate Names
      • N -4-amino-2-hydroxybutyl(lysine)
      Background InformationHypusine (N -4-amino-2-hydroxybutyl(lysine)) is derived by a post-translational modification of lysine. It is found in all eukaryotes and in certain archaea, but not in eubacteria. Currently, eukaryotic translation initiation factor5A (eIF-5A) is the only protein that has been reported to contain hypusine. This modification of elF-5A involves two reactions where in the first reaction deoxyhypusine synthase (DHS) transfers the butylamine moiety of spermidine to the -amino group of a specific lysine residue of eIF-5A resulting in the formation of deoxy-hypusine. This is followed by a hydroxylation reaction catalyzed by deoxyhypusine hydroxylase. This modification appears to be irreversible. The hypusinated form of elF-5A is reported to be the active form that is involved in translational elongation, RNA binding, and ribosome association. Hypusinated eIF5A is shown to be essential for cellular proliferation and responses to extracellular stressors. In the absence of an active hypusine cell proliferation is inhibited and Inhibition of hypusine formation is shown to confer cellular survival in certain stress states, such as infections, carcinogenesis, and obesity.
