Gingipain activity of P. gingivalis wild-type (A7436 and ATCC 33277) and pgfur mutant (TO6 and TO16) strains. Bacteria were grown under high- (Hm) or low-iron/heme (DIP) conditions in liquid culture medium for 24 h and gingipain activity in separated culture medium was determined against protease substrates specific for arginine- (Rgp) or lysine-specific (Kgp) gingipains. *P < 0.05, **P < 0.01, ***P < 0.001
