Organism
Bacillus subtilis (strain 168)
Function
Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP. It can use ATP and other nucleoside triphosphates (GTP, UTP) as well as inorganic polyphosphate (poly(P)) as a source of phosphorus.
Similarity
Belongs to the NAD kinase family.
