Nicotinamide mononucleotide adenylyltransferase 1 is an enzyme that in humans is encoded by the NMNAT1 gene.[1][2][3] It is a member of the Nicotinamide-nucleotide adenylyltransferases.

The coenzyme NAD and its derivatives are involved in hundreds of metabolic redox reactions and are utilized in protein ADP-ribosylation, histone deacetylation, and in some Ca(2+) signaling pathways. NMNAT (EC 2.7.7.1) is a central enzyme in NAD biosynthesis, catalyzing the condensation of nicotinamide mononucleotide (NMN) or nicotinic acid mononucleotide (NaMN) with the AMP moiety of ATP to form NAD or NaAD (Zhang et al., 2003).[supplied by OMIM][3]
