The mechanism for acetylation and deacetylation takes place on the NH 3+ groups of lysine amino acid residues. These residues are located on the tails of histones that make up the nucleosome of packaged dsDNA. The process is aided by factors known as histone acetyltransferases (HATs). See more Histone acetylation and deacetylation are the processes by which the lysine residues within the N-terminal tail protruding from the histone core of the nucleosome are acetylated and deacetylated as part of gene regulation See more Nucleosomes are portions of double-stranded DNA (dsDNA) that are wrapped around protein complexes called histone cores.
