WebbHistone acetylation and deacetylation is a dynamic process balanced by histone acetyltransferase (HAT) and histone deacetylase (HDAC). In general, addition of acetyl groups to histones by HATs promotes gene expression by creating an “open” chromatin conformation, while removal of acetyl groups by HDACs results in a “closed” … WebbHistone Kcr is dynamically regulated by the opposing enzymatic activities of writers and erasers. To date, no selective enzymes that directly add or remove crotonyl groups from modified lysine residues have been identified, other than previously characterised histone acetyltransferases (HATs) and histone deacetylases (HDACs) ( Table 2 ).
