WebHistone acetylation, or the addition of an acetyl group to histones, is facilitated by histone acetyltransferases (HATs) which target lysine (K) residues on the N-terminal histone tail. Histone deacetylases (HDACs) facilitate the removal of such groups. The positive charge on a histone is always neutralized upon acetylation, creating euchromatin which increases … WebPolycomb repressive complex 2 (PRC2) serves both as a “reader” and “writer” of histone PTM H3K27Me3.
