Deacylations "play crucial roles in gene transcription and most likely in all eukaryotic biological processes that involve chromatin". Acetylation is one type of post-translational modification of proteins. The acetylation of the ε-amino group of lysine, which is common, converts a charged side chain to a neutral one. Acetylation/deacetylation of histones also plays a role in gene expression and cancer. These modi… 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. cher nicolas cage in movie 1987 moonstruck
