WebHistone lysine methylation can involve the transfer of one, two or three methyl groups onto a histone tail; the degree of methylation is of biological significance since proteins that interact with methylated histones are able to distinguish between mono-, di- and trimethylated lysines. 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 …
