1DHS - 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 ...
