Protein
Deoxyhypusine synthase
Organism
Nicotiana tabacum
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. Also able to produce homospermidine from putrescine.
Similarity
Belongs to the deoxyhypusine synthase family.
