eIF5A Proteins and Enzymes

The human eukaryotic translation initiation factor 5A (eIF5A) is an 18 kDa protein. eIF5A precursor [(ec-eIF-5A(lys)] is the only cellular protein known to contain a specific lysine residue which is transformed into the unique amino acid hypusine [N-(4-amino-2-hydroxybutyl)-lysine] by a series of post translational reactions. eIF5A promotes the for...
