-==Overview==
+==Crystal structure of Mycobacterium tuberculosis NAD kinase==
-NAD kinase catalyzes the magnesium-dependent phosphorylation of NAD, representing the sole source of freshly synthesized NADP in all organisms., The enzyme is essential for the growth of the deadly multidrug-resistant, pathogen Mycobacterium tuberculosis and is an attractive target for novel, antitubercular agents. The crystal structure of NAD kinase has been solved, by multiwavelength anomalous dispersion at a resolution of 2.3 A in its T, state. Two crystal forms have been obtained revealing either a dimer or a, tetramer. The enzyme architecture discloses a novel molecular arrangement, with each subunit consisting of an alpha/beta N-terminal domain and a, C-terminal 12-stranded beta sandwich domain, connected by swapped beta, strands. The C-terminal domain shows a striking internal approximate 222, symmetry and an unprecedented topology, revealing a novel fold within the, family of all beta structures. The catalytic site is located in the long, crevice that defines the interface between the domains. The conserved GGDG, structural fingerprint of the catalytic site is reminiscent of the related, region in 6-phosphofructokinase, supporting the hypothesis that NAD kinase, belongs to a newly reported superfamily of kinases.

+== Function ==
+[https://www.uniprot.org/uniprot/NADK_MYCTU NADK_MYCTU] Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP. It can use ATP and other nucleoside triphosphates as well as inorganic polyphosphate (poly(P)) as a source of phosphorus.[HAMAP-Rule:MF_00361]<ref>PMID:11006082</ref> <ref>PMID:15182203</ref>
