?
proform pernisine + H2O
mature pernisine + signal sequence-N-terminal pro-region
the enzyme performs autoproteolytical cleavage of its N-terminal pro-region for activation

?
?
-
enzymatic degradation of protein aggregates by pernisine, such as for infective prions (PrPSc) from different origins (i.e., mouse, bovine, deer, human)

?
additional information
?
-
the propeptide is effectively degraded by the mature enzyme only at high temperatures, because it is too stable to be degraded at moderate temperatures
