| + | Caspase-6 is a cysteine protease implicated in neuronal survival and apoptosis. Deregulation of caspase-6 activity was linked to several neurodegenerative disorders including Alzheimer's and Huntington's Diseases. Several recent studies on the structure of caspase-6 feature the caspase-6 zymogen, mature apo-caspase-6 as well as the Ac-VEID-CHO peptide complex. All structures share the same typical dimeric caspase conformation. However, mature apo-caspase-6 crystallized at low pH revealed a novel, non-canonical inactive caspase conformation speculated to represent a latent state of the enzyme suitable for the design of allosteric inhibitors. In this treatise we present the structure of caspase-6 in the non-canonical inactive enzyme conformation bound to the irreversible inhibitor Z-VAD-FMK. The complex features a unique peptide binding mode not observed previously. | ||
