Table 1. Inhibition constants (K I *) of EgKU-8 acting on digestive serine proteases.

Target enzyme K I * (pM)a
Bovine
Cationic trypsin 60±13
Chymotrypsin A 2050±170
Canine
Anionic trypsin 17±4
Cationic trypsin 22±8
Chymotrypsin B NIb
a

K I *, the global equilibrium dissociation constants, were calculated from inhibition assays (see Figure 4A) according to equation 1 for tight-binding inhibitors and minimally corrected for the effect of substrate concentration according to equation 2. Values correspond to averages of independent measurements ± the standard error (n≥3).

b

NI, not inhibited.
