Accepted name: Lys-Lys/Arg-Xaa endopeptidase
Reaction: Cleavage of -Lys-Lys┼ and -Lys-Arg┼ bonds.
Other name(s): ASP (Aeromonas sobria)-type peptidase; Aeromonas extracellular serine protease
Comments: The enzyme is a serine peptidase, which has been shown to cleave prothrombin and prekallikrein. It hydrolyses the complement component C5 releasing complement component C5a.
