Can proteins be 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.

WebJul 3, 2024 · Protein acetylation commonly has two different forms. In humans, almost (80%-90%) proteins become co-translationally acetylated at their Nα-termini of the nascent polypeptide chains. Another type is … inconsistent dry coughProteins are typically acetylated on lysine residues and this reaction relies on acetyl-coenzyme A as the acetyl group donor. In histone acetylation and deacetylation, histone proteins are acetylated and deacetylated on lysine residues in the N-terminal tail as part of gene regulation.
