Eukaryotic initiation factor 5A (eIF-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 (DS) EC:1.1.1.249. The modified version of eIF-5A, and DS, are required for eukaryotic cell proliferation [1].	Domain
E	PF01287	Eukaryotic elongation factor 5A hypusine, DNA-binding OB fold (eIF-5a)	Eukaryotic elongation factor 5A hypusine, DNA-binding OB fold	eIF5A, previously thought to be an initiation factor, has been shown to be required for peptide chain elongation in yeast [1].	Domain
