Environ. Microbiol. 75:2046-2056(2009). 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=NAD(+) + ATP = ADP + NADP(+) + H(+); 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}.
