Protein attributes

Sequence length	369 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Catalyzes the NAD-dependent oxidative cleavage of spermidine and the subsequent transfer of the butylamine moiety of spermidine to the epsilon-amino group of a specific lysine residue of the eIF-5A precursor protein to form the intermediate deoxyhypusine residue.
Catalytic activity	[eIF5A-precursor]-lysine + spermidine = [eIF5A-precursor]-deoxyhypusine + propane-1,3-diamine.
Cofactor	NAD.
Pathway	Protein modification; eIF5A hypusination.
Subunit structure	Homotetramer formed by a dimer of dimers. Ref.10 Ref.15 Ref.16
Post-translational modification	Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.12
Sequence similarities	Belongs to the deoxyhypusine synthase family.
