Cellular membranes contain numerous lipids, and efforts to understand the biological functions of individual lipids demand approaches for controlled modulation of membrane composition in situ. Now, click chemistry-based directed evolution of a microbial phospholipase within mammalian cells affords an editor for optogenetic, targeted modification of phospholipids in cell membranes.
