Effect of pH on CuZnSOD acitivity. Purified recombinant C. burnetii CuZnSOD was assayed for its ability to inhibit the reduction of cytochrome c at pH 5.0, (A); pH 7.0, (B); and pH 9.0, (C). Open circles represent the reduction of cytochrome C in the absence of SOD. Closed circles represent the reduction of cytochrome C in the presence of SOD.
