摘要: Hypusine is a derivative of lysine which occurs in single cellular protein, eIF-4D1. This unusual basic amino acid was discovered 1971 extracts bovine brain by Shiba and coworkers, who determined its chemical structure as Ne-[4-amino-2-hydroxybutyl]lysine.2 Subsequently, occurrence the free component protein various animal tissues reported. Ten years later, we observed radiolabeling (Mr; ~18,000, pI; ~5.3) human peripheral lymphocytes following their incubation with [3H]spermidine identified radioactive this hypusine.5 Based on finding commenced systematic studies hypusine-containing mechanism regulation biosynthesis hypusine.
