WebProtein acylation processes involve the covalent attachment of acyl moieties to the alpha- and epsilon-amino groups of polypeptide chains. The N-terminal blocking of proteins occurs in a wide range of eukariotic cells, where more than 50% of the cytosolic proteins can be N-alpha-acetylated. WebProtein acetylation is another very common protein modification. Here, the acetyl group is co- or posttranslationally attached either to the lysine residues at ɛ-amino group or to the N-terminus of protein at α-amino group. Lysine acetylation and deacetylation of proteins was widely studied in histones first.
