DHPS tetramer synthesizes EIF5A and spermidine from Dhp-K50-EIF5A [GO_0034038]

Catalysis of the reaction: [eIF5A-precursor]-lysine + spermidine = [eIF5A-precursor]-deoxyhypusine + propane-1,3-diamine. Four sub-reactions have been identified,in which the intermediates remain tightly associated with the enzyme: spermidine + NAD+ = dehydrospermidine + NADH; dehydrospermidine + [enzyme]-lysine = N-(4-aminobutylidene)-[enzyme]-lysine + propane-1,3-diamine; N-(4-aminobutylidene)-[enzyme]-lysine + [eIF5A-precursor]-lysine = N-(4-aminobutylidene)-[eIF5A-precursor]-lysine + [enzyme]-lysine; N-(4-aminobutylidene)-[eIF5A-precursor]-lysine + NADH + H+ = [eIF5A-precursor]-deoxyhypusine + NAD+. Note that this term is equivalent to the obsolete molecular function term ‘deoxyhypusine synthase activity ; GO:0004171’ and corresponds closely to the biological process term ‘deoxyhypusine biosynthetic process from spermidine, using deoxyhypusine synthase ; GO:0050983’.
