WebJun 2, 2015 · Acetyl-CoA is a membrane-impermeant molecule constituted by an acetyl moiety (CH 3CO) linked to coenzyme A (CoA), a derivative of vitamin B5 and cysteine, through a thioester bond (Shi and Tu, 2015 ). WebLysine acetylation can have wide-reaching effects. Acetylation of lysines can alter the three-dimensional structure of a protein, affecting its ability to bind other proteins or DNA. Furthermore, acetylation can have an impact on the subcellular localization, activity, and stability of a protein.
