- Oslobađanje maturisanih proteina iz njihovih proproteina razlaganjem -Arg-Xaa-Yaa-Arg- veza, gde Xaa može da bude bilo koja aminokiselina, dok je Yaa: Arg ili Lys. Oslobađa se albumin, komplementna komponenta C3 i von Vilebrandov faktor iz njihovih prekursora
Ova grupa peptidaza je strukturno i funkcionalno slična sa keksinom.
