Activity Regulation
Binding Site
Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.; EC=3.4.22.1;
DNA Binding
EC Number 3.4.22.1
Enzyme Function FUNCTION: Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Has also been implicated in tumor invasion and metastasis.
