Webb16 juni 2024 · Histone acetylation and deacetylation are key events in the regulation of chromatin structure. Additionally, Histone acetyltransferases (HATs) can catalyze acetyl groups to the ε-amino terminus of lysine residues within histones. Acetylation results in an open chromatin structure by removing positive charges from histones.
