  • PubMed Abstract: 
  • Eukaryotic initiation factor 5A (elF-5A) contains an unusual amino acid, hypusine [N epsilon-(4-aminobutyl-2-hydroxy)lysine]. The first step in the post-translational formation of hypusine is catalysed by the enzyme deoxyhypusine synthase (DHS). The modified version of elF-5A, and DHS, are required for eukaryotic cell proliferation ...

    Eukaryotic initiation factor 5A (elF-5A) contains an unusual amino acid, hypusine [N epsilon-(4-aminobutyl-2-hydroxy)lysine]. The first step in the post-translational formation of hypusine is catalysed by the enzyme deoxyhypusine synthase (DHS). The modified version of elF-5A, and DHS, are required for eukaryotic cell proliferation. Knowledge of the three-dimensional structure of this key enzyme should permit the design of specific inhibitors that may be useful as anti-proliferative agents.
