WebAug 3, 2024 · Histone acetylation is the addition of an acetyl group, a three-carbon molecule, to a lysine "residue" at one end of a histone molecule. Lysine is an amino acid, and the 20 or so amino acids are the building blocks of proteins. This is catalyzed by the enzyme histone acetyltransferase (HAT).
