NADH oxidation assays using inverted membrane vesicles from strains AKD788 (only expressed terminal oxidase CydAB; white bars) and AKD789 (only expressed terminal oxidase AOX; gray bars). Vesicles were prepared from aerobically grown log-phase cells and assayed at 23 °C. NADH oxidation rate is reported as µmol NADH oxidized per minute, per mg of protein. Samples were either not treated with exogenous chemicals (untreated), treated with 80 µM DEA NONOate (NO), or 3 mM potassium cyanide (KCN). Data presented are the average rates from three independent sets of cultures from two separate experiments performed on different days. Error bars represent standard error of the mean. Asterisks indicate statistically significant differences (p < 0.002) from the corresponding untreated samples as determined using a student’s t-test
