Webb27 jan. 1998 · Activation requires proteolytic cleavage of the caspases at specific sites, and in most cases, these sites are themselves substrates for caspases. So, by analogy to coagulation, death is controlled by a cascade of proteases acting on each other. The promise of this as a therapeutic pathway emerges from two sources. WebbAspartate-specific cysteine proteases, the so-called ‘caspases’, are the main enzymes involved in this process. At least ten homologues of interleukin-1β converting enzyme (ICE), the first described human caspase, have been identified so far. orchards of lyon hoa https://maamoskitchen.com
