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 H2O2-mediated oxidative stress[1]. NPO provides an additional pathway for regeneration of NAD+ which is essential to the fermentative metabolism. FAD is the cofactor in this reaction.
