Protease activation cascade
Webb12 jan. 1999 · These death proteases are part of a proteolytic caspase cascade that is activated by diverse apoptotic stimuli from outside and inside of the cell. 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.

A cascade of zymogen activations activates a clotting factor, which is then responsible for activating another clotting factor and so forth until the final clot is achieved. The blood clotting process is driven by a series of proteolytic events.
Webb3 nov. 2006 · In addition, trypsin also triggers a cascade activation of other proteolytic enzymes, and the resulting mixture of enzymes includes endopeptidases (trypsin, chymotrypsin, and elastase) and exopeptidases (carboxypeptidases A and B). Thus, the formation of trypsin by enteropeptidase is the essential activation step . General Note— WebbA protease is an enzyme that cuts a protein into smaller pieces.
