Because eIF5A did not stimulate earlier steps of translation initiation 8, ... Hypusine is an uncommon amino acid found in all eukaryotes and in some archaea, but not in bacteria. The only known proteins containing the hypusine residue is eukaryotic translation initiation factor 5A (eIF-5A) and a similar protein found in archaea. In humans, two isoforms of eIF-5A have been described: eIF5A-1 and eIF5A-2. They are encoded by two distinct genes EIF5A and EIF5A2. The protein is involved in protein biosynthesis and promotes the formation of the first pe…
WebEIF5A is an essential gene that encodes a protein that is approximately 17 kDa in size and is conserved among eukaryotes and archaebacteria [97]. EIF5A is the only known protein that is modified at a specific lysine residue to yield hypusine. Although EIF5A has been extensively studied, its biological role has not been fully elucidated.
WebThe novel amino acid hypusine is a posttranslational modification (PTM) that occurs in eukaryotic initiation factor 5A (EIF5A) at a specific lysine residue.
