Abstract

Interleukin-1 beta (IL-1 beta)-converting Enzyme cleaves the IL-1 beta precursor to mature IL-1 beta, an important mediator of inflammation. The identification of the Enzyme as a unique cysteine protease and the design of potent peptide aldehyde inhibitors are described. Purification and cloning of the complementary DNA indicates that IL-1 beta-converting Enzyme is composed of two nonidentical subunits that are derived from a single proenzyme, possibly by autoproteolysis. Selective inhibition of the Enzyme in human blood monocytes blocks production of mature IL-1 beta, indicating that it is a potential therapeutic target.
