WebHistone acetyltransferases and deacetylases are, respectively, the enzymes devoted to the addition and removal of acetyl groups from lysine residues on the histone N-terminal tails. The enzymes exert fundamental roles in developmental processes and their deregulation has been linked to the progression of diverse human disorders, including cancer. WebThe addition of the acetyl group neutralizes this positive charge and hence reduces the binding between histones and DNA, leading to a more open structure which is more accessible to the transcriptional machinery. Histone acetylation therefore leads to transcriptional activation.
