Abstract: The post-translational modification of histones plays an important role in chromatin regulation, a process that insures the fidelity of gene expression and other DNA transactions. Of the enzymes that mediate post-translation modification, the histone acetyltransferase (HAT) and histone deacetylase (HDAC) proteins that add and remove acetyl groups to and from target lysine residues within histones, respectively, have been the most extensively studied at both the functional and structural levels. Not surprisingly, the aberrant activity of several...
