Loss of MnSOD activity in Mn-deficient cells. Twenty micrograms of total soluble protein was loaded onto a nondenaturing polyacrylamide gel and analyzed for SOD activity in extracts of cells grown in medium with the indicated manganese concentrations. Two- and 4-fold dilutions of the 25-μm sample are included for relative activity comparison. All experiments were performed in experimental triplicate.
