CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of proteins with broad specificity for peptide
CC bonds. Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule
CC substrates (thus differing from cathepsin L). In addition to being an
CC endopeptidase, shows peptidyl-dipeptidase activity, liberating C-
CC terminal dipeptides.; EC=3.4.22.1;
CC Evidence={ECO:0000256|ARBA:ARBA00001754};
CC -!- SIMILARITY: Belongs to the peptidase C1 family.
CC {ECO:0000256|ARBA:ARBA00008455}.
