WebJan 1, 2024 · Histone acetylation is a highly dynamic modification regulated by the opposing actions of two families of enzymes, namely histone acetyltransferases (HATs) and histone deacetylases (HDACs) [14]. All HATs utilize acetyl CoA as cofactor in the enzymatic reaction, and they can be divided into two classes defined by their cellular localization.
