What is the Role of Enzymes in Histone Modification?
Enzymes play a pivotal role in histone modifications. Histone acetyltransferases (HATs) add acetyl groups to histones, while histone deacetylases (HDACs) remove them. Similarly, histone methyltransferases (HMTs) add methyl groups, and histone demethylases (HDMs) remove them. These enzymes act as biological catalysts, facilitating the addition or removal of functional groups on histone proteins.
