| + | '''NADH peroxidase''' (NPO) catalyzes the conversion of NADH to NAD+ using hydrogen peroxide. See [[NAD]]. NPO eliminates the potentially toxic hydrogen peroxide and defends the cell against H<sub>2</sub>O<sub>2</sub>-mediated oxidative stress<ref>PMID:8425532</ref>. NPO provides an additional pathway for regeneration of NAD+ which is essential to the fermentative metabolism. FAD is the cofactor in this reaction. | ||
