Chains	Enzyme Name	Description	Catalytic Residues
A, B	caspase-1 M-CSA #718	Caspases are thiol endopeptidases that cleave specific proteins after Asp residues and drive apoptosis or inflammation. Caspase-1 is part of the family of inflammatory-caspases, which also includes caspase-4 and caspase-5 in humans and caspase-11, -12, -13 and -14 in mice. Activation of caspase-1 requires oligomerisation of inactive monomeric proenzyme forms. Caspase-1 has a recognition site of Tyr-Val-Ala-Asp-\|-. Caspase-1 is also known as interleukin converting enzyme (ICE) and cleaves precursors of the inflammatory interleukin1β and interleukin18 which converts them into mature, active peptides which can initiate a proinflammatory pathway. These often contribute to the pathophysioiogy of many inflammatory and autoimmune diseases, including septic shock, rheumatoid arthritis, and insulin-dependent diabetes mellitus.
