BRITE hierarchy
Reaction(IUBMB)
Preferential cleavage: Arg!, Lys!, but with more restricted specificity than trypsin
Comment
Occurs as a tetrameric molecule with high affinity for heparin, in mast cell granules. In peptidase family S1 (trypsin family). Not inhibited by alpha1-proteinase inhibitor or alpha2-macroglobulin
