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. It can use ATP and other
CC nucleoside triphosphates as a source of phosphorus. NADH cannot replace
CC NAD as a substrate. {ECO:0000255|HAMAP-Rule:MF_00361,
CC ECO:0000269|PubMed:16682646}.
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 ECO:0000269|PubMed:16682646};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00361,
CC ECO:0000269|PubMed:16682646};
CC -!- ACTIVITY REGULATION: Allosterically inhibited by NADPH and NADH. NADPH
CC is the primary inhibitor during aerobic growth and NADH during
CC anaerobic growth. {ECO:0000269|PubMed:16682646}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=2.1 mM for NAD {ECO:0000269|PubMed:16682646};
CC KM=2.7 mM for ATP {ECO:0000269|PubMed:16682646};
CC -!- SUBUNIT: Equilibrium mixture of dimer and tetramer. It is converted
CC entirely to tetramer in the presence of the inhibitor NADPH.
CC {ECO:0000269|PubMed:16682646, ECO:0000269|Ref.3}.
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}.
