Glutamine-dependent NAD(+) synthetase is an enzyme that in humans is encoded by the NADSYN1 gene.Nicotinamide adenine dinucleotide (NAD) is a coenzyme in metabolic redox reactions a precursor for several cell signaling molecules and a substrate for protein posttranslational modifications. NAD synthetase (EC 6.3.5.1) catalyzes the final step in the biosynthesis of NAD from nicotinic acid adenine dinucleotide (NaAD).
