- obsolete kexin activity
OBSOLETE. Catalysis of the cleavage of the Arg-Xaa bond in Lys-Arg-Xaa and Arg-Arg-Xaa to process Yeast alpha-factor pheromone and killer toxin precursors.
- obsolete nardilysin activity
OBSOLETE. Catalysis of the hydrolysis of polypeptides, preferably at the first bond of Xaa-Arg-Lys, and less commonly at the first bond of Arg-Arg-Xaa, in which Xaa is not Arg or Lys.
- obsolete plasma kallikrein activity
OBSOLETE. Catalysis of the selective cleavage of Arg-Xaa and Lys-Xaa bonds, including Lys-Arg and Arg-Ser bonds in (human) kininogen to release bradykinin.
