FEBS letters, 1996•ElsevierDeoxyhypusine synthase is essentially required for the post-translational formation of
hypusine, a modification of a specific lysine residue in eukaryotic initiation factor 5A, which
appears to be pivotal for cell proliferation. From a human peripheral blood mononuclear
cells cDNA library we isolated two independent sequences encoding biologically active
deoxyhypusine synthase. DNA sequence analysis revealed a 369 amino acid protein with a
molecular mass of 41.055 kDa. This recombinant deoxyhypusine synthase showed …

Deoxyhypusine synthase is essentially required for the post-translational formation of hypusine, a modification of a specific lysine residue in eukaryotic initiation factor 5A, which appears to be pivotal for cell proliferation. From a human peripheral blood mononuclear cells cDNA library we isolated two independent sequences encoding biologically active deoxyhypusine synthase. DNA sequence analysis revealed a 369 amino acid protein with a molecular mass of 41.055 kDa. This recombinant deoxyhypusine synthase showed significant catalytic activity in synthesis of deoxyhypusine after in vitro transcription and translation as well as upon expression in Escherichia coli. Using a panel of somatic rodent-human cell hybrids we localized the deoxyhupusine synthase gene to human chromosome 19.
