TABLE 2.
Comparison of inhibitory potential of PnBBI and soybean BBI toward Bovine trypsin, chymotrypsin and trypsin-like midgut proteases of H. armigera (HaTPs).
| Protease | Half-maximal inhibitory concentration (IC50) |
|
| PnBBI (μg) | Soybean BBI (μg) | |
| Bovine trypsin | 0.730 ± 0.01 | 3.4 ± 0.09 |
| Chymotrypsin | 17.54 ± 0.92 | 16.1 ± 0.85 |
| HaTPs | 0.040 ± 0.003 | 16.5 ± 0.65 |
The data represented is mean ± SE of three biological replicates. IC50 is defined as the amount of inhibitor required to inhibit half of the corresponding protease activity.
