CC   -!- FUNCTION: Involved in the regulation of the intracellular balance of
CC       NAD and NADP, and is a key enzyme in the biosynthesis of NADP.
CC       Catalyzes specifically the phosphorylation on 2'-hydroxyl of the
CC       adenosine moiety of NAD to yield NADP. {ECO:0000255|HAMAP-
CC       Rule:MF_00361}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + NAD(+) = ADP + H(+) + NADP(+); Xref=Rhea:RHEA:18629,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:57540,
CC         ChEBI:CHEBI:58349, ChEBI:CHEBI:456216; EC=2.7.1.23;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00361};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00361};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00361}.
CC   -!- SIMILARITY: Belongs to the NAD kinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00361}.
