Abstract

NAD kinase catalyzes the phosphorylation of NAD(H) to form NADP(H), using ATP as phosphoryl donor. It is the only key enzyme leading to the de novo NADP(+)/NADPH biosynthesis. Coenzymes such as NAD(H) and NADP(H) are known for their important functions. Recent studies have partially demonstrated that NAD kinase plays a crucial role in the regulation of NAD(H)/NADP(H) conversion. Here, the molecular properties, physiologic functions, and potential applications of NAD kinase are discussed.
