It was believed that N-terminal acetylation protects proteins from being degraded as Nα-acetylation N-termini were supposed to block N-terminal ubiquitination and subsequent protein degradation.
Críase que a acetilación N-terminal protexía as proteínas da degradación, xa que se supoñía que a Nα-acetilación N-terminal bloqueaba a ubiquitinación N-terminal e a subseguinte degradación de proteínas.
