The cover image illuminates the non-enzymatic “ghost writers” of lysine acylation. Meier et al. detail the development of a chemoproteomic strategy that harnesses thioester reactivity to discover candidate cellular targets of non-enzymatic acylation. Application of this approach reveals that glycolytic enzymes can be strongly inhibited by reactive thioesters, including the fatty acid precursor malonyl-CoA. This study provides new insights into the metabolic regulation of lysine acetylation, and highlights the utility of reactivity-based methods to define and manipulate non-enzymatic protein modifications in complex biological settings.
