A paradox of modern acetylation biology is that the while number of sites of acetylation has climbed rapidly, the number of enzymes thought to catalyze this process has stayed relatively constant. Here we describe the utility of chemical proteomic methods to discover and characterize novel mechanisms of acetylation in endogenous cellular contexts. Our studies highlight an expanded landscape of regulatory acetylation in gene expression control, as well as new strategies to investigate the metabolic regulation and small molecule inhibition of acetyltransferases in cells.
