by destroying proteinase inhibitors at the same time as it activates endogenous proteinases , bitis arietans metalloproteinase would appear to be particularly useful for studies of the activation of inactive renin in human plasma , since endogenous proteinases are then free to activate inactive renin without subsequent inhibition by endogenous proteinase inhibitors .
