Effect of pH in proteolytic processing of Cyt1Ab1 toxin

The proteolysis of the Cyt1Ab1 toxin was tested on buffers of different pH. The toxin showed a little activation at pH 10.6 and 11 with C. quinquefasciatus gut extract, trypsin and chymotrypsin, a complete activation of toxin at defined fragments were seen at pH 12.
