Comments [?]

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.
Catalytic activity RHEA:18629: ATP + NAD(+) = ADP + H(+) + NADP(+)
EC 2.7.1.23
Cofactor a divalent metal cation
Subcellular location Cytoplasm.
Similarity Belongs to the NAD kinase family.
