WebHistones are composed of mostly positively charged amino acid residues such as lysine and arginine. The positive charges allow them to closely associate with the negatively charged DNA through electrostatic interactions. Neutralizing the charges in the DNA allows it to become more tightly packed. [6] Interactions with the minor groove [ edit] WebSep 13, 2024 · The complex formed by proteins and DNA is called chromatin. Tight wrapping of DNA around histones prevents its access to various chromosomal regulatory proteins, leading to gene silencing.

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.
