WebHistone methylation is a stable mark propagated through multiple cell divisions, and for many years was thought to be irreversible. However, it was recently discovered to be an … WebHistone acetyltransferases (HATs) are a class of enzymes that instigate the formation of euchromatin from heterochromatin. HATs catalyze the transfer of an acetyl group (CH 3 CO) to a conserved lysine on the histone tail. Acetylation of histones typically leads to relaxed chromatin and is associated with activation of transcription.
