The 97-kDa protein Mtx21, derived from the 100-kDa mosquitocidal protein (Mtx) from Bacillus sphaericus SSII-1 by the deletion of the putative signal sequence, was expressed as a fusion protein with glutathione S-transferase in Escherichia coli, and the fusion protein was purified by affinity chromatography. The fusion protein bound to glutathione agarose was cleaved with thrombin to release the Mtx21 protein. The 97-kDa Mtx21 protein was found to be toxic to Culex quinquefasciatus larvae with… CONTINUE READING
