Portease purification and characterization of a serine inhibitor from Egyptian varieties of soybean seeds and its efficacy against Spodoptera littoralis.
Serine inhibitors have been described in many plant species and are universal throughout the plant kingdom. Trypsin inhibitors are the most common type. In the present study, trypsin and chymotrypsin inhibitory activity was detected in the seed flour extracts of four Egyptian varieties of soybean (Glycine max). The soybean variety, Giza 22, was found to have higher trypsin and chymotrypsin ... Read more

Biochemical characterization of the midgut serine proteases of the Egyptian cottonworm, Spodoptera littoralis (Boisduval) and their interactions with standard protease inhibitors
Serine proteolytic activities in soluble protein extracted from the larval midgut of Spodoptera littoralis were studied using specific substrates and protease inhibitors. There are significant differences in serine activities in respect to larval development. The serine activities increase with instar development, reach each maximum at third instar larvae while the lowest serine activities are observed in the fifth instar larvae. ... Read more
