Reversal of targeted deacetylation occurs within 5–8 min, whereas reversal of targeted acetylation is more rapid, taking 1.5 min. hotels near love airport dallas

"Proteins 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. Typically, these reactions are catalyzed by enzymes with histone acetyltransferase (HAT) or hist… " - Protein deacetylation
