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:0000256|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:0000256|ARBA:ARBA00001262, ECO:0000256|HAMAP-
CC Rule:MF_00361};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00361};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00361}.
CC -!- SIMILARITY: Belongs to the NAD kinase family. {ECO:0000256|HAMAP-
CC Rule:MF_00361}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00361}.
