Figure 5. Relationship of the rate of λ-crystallin-enhanced NADH oxidation by superoxide generated enzymatically to concentration of partially purified λ-crystallin
NADH oxidation rates were determined at 50 μM NADH with or without partially purified λ-crystallin (0-163 μg protein/ml). Superoxide was generated at an initial rate of 0.7 μM/min by 20 μM xanthine and 5.5 μg/ml xanthine oxidase.
