Tryptase
Definition:

Tryptase is a mast-cell-granule trypsin-family (S1) serine protease that occurs as a heparin-affinity tetramer and is not inhibited by alpha1-proteinase inhibitor or alpha2-macroglobulin; it preferentially cleaves Arg and Lys bonds but with more restricted specificity than trypsin. By degrading neuropeptides and extracellular matrix it drives allergic and inflammatory reactions. It appears in viruses and cellular organisms.
