Activation of plasminogen bound to F. nucleatum subsp. nucleatum^a

Activator	Mean A405 ± SEMa
	Coated with plasminogen	Uncoated (control)
None	0.056 ± 0.010	0.045 ± 0.012
Streptokinase (500 U/ml)	0.518 ± 0.031	0.051 ± 0.006
Urokinase (0.15 U/ml)	0.644 ± 0.046	0.057 ± 0.007
P. gingivalis culture supernatant (1:5)	0.171 ± 0.018	0.066 ± 0.009

^aHydrolysis of the plasmin chromogenic substrate by F. nucleatum subsp. nucleatum was measured. Values are the results of two independent experiments performed in duplicate. A₄₀₅, absorbance at 405 nm.
