Function and Biology Details
Reaction catalysed:
Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg-|- bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.
