CC   -!- FUNCTION: Catalyzes the phosphorylation of NAD to NADP. Utilizes
CC       ATP and other nucleoside triphosphates as well as inorganic
CC       polyphosphate as a source of phosphorus (By similarity).
CC   -!- CATALYTIC ACTIVITY: ATP + NAD(+) = ADP + NADP(+).
CC   -!- COFACTOR: Divalent metal ions (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the NAD kinase family.
