Description_x000D_ General description_x000D_ NAD kinase catalyzes the transfer of a phosphate group from ATP to NAD+ to generate NADP+, which in its reduced form acts as an electron donor for biosynthetic reactions. NADP+ is an essential coenzyme in metabolism and provides reducing power to biosynthetic processes such as fatty acid biosynthesis._x000D_ Physical form_x000D_ Ammonium sulphate suspension._x000D_ Other Notes_x000D_ Human full length NAD kinase (aa 1-446) is fused at the N-terminus to a His-tag.
