Activities of Cox2 and the supercomplex

Cytochrome c oxidation Cytochrome c reduction in the presence of cyanide Ubiquinol oxidation
Cox2 0.41 ± 0.01 0.18 ± 0.04 1.22 ± 0.13
Supercomplex 1.16 ± 0.12 2.12 ± 0.34 0.96 ± 0.23

The enzymatic reactions were measured spectrophotometrically at 80 °C. Specific activities are shown by mean ± standard error from three measurements. The unit of micromole per minute per milligram was applied.
