Function and Biology Details

Reaction catalysed: 
Release of mature proteins from their proproteins by cleavage of -Arg-Xaa-Yaa-Arg-|- bonds, where Xaa can be any amino acid and Yaa is Arg or Lys. Releases albumin, complement component C3 and von Willebrand factor from their respective precursors.
