Reduction of the chromophores of mitochondrial NADH-ubiquinone reductase by NADPH reaches only 50% of the extent of reduction by NADH, monitored at 450 nm. This effect is due to autoxidation of an enzyme component at a higher rate than its reduction by NADPH.
在450纳米处监测发现,烟酰胺腺嘌呤二核苷酸磷酸(NADPH)对线粒体烟酰胺腺嘌呤二核苷酸(NADH)-泛醌还原酶发色团的还原程度仅达到NADH还原程度的50%。这种效应是由于酶成分的自氧化速率高于其被NADPH还原的速率。
