NADH generation per H2O2 generation |
|---|---|---|---|
| 0 | 46 ± 2.8 | 0.15 ± 0.02 | 307 |
| 0.2 | 29.2 ± 2.3 | 2.58 ± 0.11 | 11.4 |

Experiments were performed as described for Figure 3, a and c, but NADH plus NAD+ was applied in different ratios at 500 μm NADH plus NAD+ concentration.
Values are mean ± SEM from three experiments.
