CC -!- FUNCTION: The precise role of eIF-5A in protein biosynthesis is not
CC known but it functions by promoting the formation of the first peptide
CC bond.
CC -!- PTM: Lys-52 undergoes hypusination, a unique post-translational
CC modification that consists in the addition of a butylamino group from
CC spermidine to lysine side chain, leading to the formation of the
CC unusual amino acid hypusine. eIF-5As are the only known proteins to
CC undergo this modification, which is essential for their function.
CC {ECO:0000250|UniProtKB:Q9XI91}.
CC -!- SIMILARITY: Belongs to the eIF-5A family. {ECO:0000305}.
