Bacillus thuringiensis crystal delta-endotoxin: role of proteases in the conversion of protoxin to toxin.

V Rukmini1, C Y Reddy, G Venkateswerlu.   

Abstract

The conversion of delta-endoprotoxins of Bacillus thuringiensis to active toxins is mediated by trypsin, insect gut (exogenous) and bacterial (endogenous) proteases. The biochemical aspects of exogenous and endogenous proteases involved in the conversion of protoxin to toxin are reviewed. Perhaps, these proteases also play a role in influencing the host range of toxin and in the development of resistance to toxin.
