RT   "Cassava translation initiation factor 5A (eIF-5A).";
RL   Submitted (NOV-2000) to the EMBL/GenBank/DDBJ databases.
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-53 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}.
