FIG. 4.
Effect of phenyl phosphorodiamidate concentration on the rate of inactivation of AtzF, yielding Ki (1/Kinac). Insert, time-dependent inhibitory effect of different concentrations of phenyl phosphorodiamidate on AtzF activity. Legend: 0.25 mM (•), 1.25 mM (▪), 2.5 mM (▴), and 5 mM (▾) phenyl phosphorodiamidate.
