* This calculation involved only active PSPs: POP, DPP 4, DPP 8, PRCP, APP1, APP2, APP3, and XPD. DPP 10 was not included because it is an inactive DPP 4 homolog and does not possess peptidase activity. LAP and CND were not included because cleavage of post-proline bonds is not their main specificity.
