- Ovaj enzim deluje na supstrate koji su bar delimično denaturisani. P1 ostatak mesta razlaganje je normalno između para hidrofobnih ostataka, kao što su Val-Val
Ova serinska endopeptidaza je esencijalna za razlaganje denaturisanih ili agregiranih proteina sa unutrašnje membrane i periplazmičnog prostora u Escherichia coli.
