CC   -!- FUNCTION: Catalyzes the NAD-dependent oxidative cleavage of spermidine
CC       and the subsequent transfer of the butylamine moiety of spermidine to
CC       the epsilon-amino group of a specific lysine residue of the eIF-5A
CC       precursor protein to form the intermediate deoxyhypusine residue.
CC       {ECO:0000255|HAMAP-Rule:MF_00153}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[eIF5A protein]-L-lysine + spermidine = [eIF5A protein]-
CC         deoxyhypusine + propane-1,3-diamine; Xref=Rhea:RHEA:33299, Rhea:RHEA-
CC         COMP:10143, Rhea:RHEA-COMP:10144, ChEBI:CHEBI:29969,
CC         ChEBI:CHEBI:57484, ChEBI:CHEBI:57834, ChEBI:CHEBI:82657; EC=2.5.1.46;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00153};
CC   -!- COFACTOR:
CC       Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00153};
CC   -!- PATHWAY: Protein modification; eIF5A hypusination. {ECO:0000255|HAMAP-
CC       Rule:MF_00153}.
CC   -!- SIMILARITY: Belongs to the deoxyhypusine synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00153}.
