Functional Description
 Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down- regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin.
