NAD+ synthase
Definition:
EC Tree > 6 Ligases > 6.3 Forming carbon-nitrogen bonds > 6.3.1 Acid—ammonia (or amine) ligases (amide synthases) > 6.3.1.5 NAD+ synthase
NAD+ synthase (NadE/NadD) amidates deamido-NAD+ to NAD+; L-glutamine can act, more slowly, as amido-donor (cf. EC 6.3.5.1 glutamine amidotransferase type). It uses ammonia directly: ATP plus deamido-NAD+ plus ammonia yields AMP plus diphosphate plus NAD+. It is found in Bacteria, Archaea and Eukaryota. Structurally it is a NadE-type amidoligase.
