The novel amino acid hypusine is a post-translational modification that only appears in a single small acidic protein in the eukaryotic initiation factor 5A (EIF-5A). Within two subsequent enzymatic steps, a specific lysine residue is modified by the enzymes deoxyhypusine synthase (DHS, EC 2.5.1.46) and deoxyhypusine hydroxylase (DOHH, EC 1.14.99.29). Hypusination is strictly linked to the polyamine pathway. While in the first step, under DHS catalysis, an aminobutyl moiety from the triamine spermidine is transferred to the e-amino group of a specific lysine in eIF-5A (Lys 50 in EIF-5A), DOHH completes hypusine biosynthesis by hydroxylation of the side chain in 2-position and thus activates eIF-5A in the second step. EIF-5A has a central role in translation elongation facilitating peptide bound formation during translation of polyproline-containing proteins. Findings of a genome-wide analysis of 35 representative organisms from six kingdoms of life, that is, archaebacteria, eubacteria, protista, fungi, plantae, and animalia showed that EIF-5A-dependent expression is strongly associated with specific biological processes like actin/cytoskeletal associated functions, RNA splicing/turnover, DNA binding/transcription, and cell signaling. |
