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 |
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).
NI, not inhibited.
