Effect of insecticidal crystal proteins of Bacillus thuringiensis var. israelensis on the enzymes of rat intestinal brush border membrane vesicles.
In vivo treatment of intestinal brush border membrane vesicles with solubilized insecticidal crystal proteins (ICP) from the two strains of B. thuringiensis var. israelensis (VCRC B17 and VCRC MB24) caused no adverse effect on gamma glutamyl transpeptidase, Na+K+ATPase, sucrase and lactase enzymes. But, exposure of membrane vesicles to solubilized ICP's in vitro, lead to significant reduction in the activity of Na+K+ATPase, sucrase and lactase enzymes.
