Going through a phase

Genetic screens uncover a bioactivation pathway for Lasonolide A involving enrichment in lipid droplets and cleavage into a cytotoxic, soluble metabolite by a lipid droplet-associated serine hydrolase. These findings identify enzymatically regulated phase partitioning as a drug activation mechanism.
