Courtesy of David S. GoodsellHistone deacetylases (HDACs), closely associated with gene silencing, may have a broader role in the cell than previously thought. Research suggests that HDACs have been misclassified simply because histones were the first substrates identified for these enzymes.Holly Goodson and colleagues, University of Notre Dame, dug through genome databases and characterized the prokaryotic distribution of HDAC homologs, providing evidence that these proteins predate eukaryote e
