crystallography to bind a putative allostericsite at the dimer interface. A fragment‐merging strategy was employed to produce nanomolar‐affinity ligands that contact residues in the L2 loop at the dimer interface, significantly stabilizing procaspase‐6. Because rearrangement of the L2 loop is required for caspase‐6 activation, our results suggest a strategy for the allosteric control of caspase activation
